Project for Human Development raises alarm over abortion plans by UNFPA

At a press conference in Lagos, Director- General of a PRO-LIFE non-governmental organisation, The Project for Human Development, PHD, Jerry Okwuosa raised an alarm over alleged plans by the United Nations Population Funds, UNFPA, to reduce the Nigerian population by offering abortion services to pregnant women and girls recently rescued from Boko Haram by the Nigerian Armed Forces. He condemned any attempt to subject the pregnant women and girls in the Internally Displaced Persons, IDPs, camps to a traumatic, violent-wrecking and life-threatening abortion process. Okwuosa who accused UNFPA of having hidden intentions which is to reduce the population of Nigeria said: “We are aware that currently UNFPA is providing counselling to these Nigerians in the displacement camps in Borno State. Also reproductive health kits and dignity kits have also been deployed in Borno and Adamawa states to support safe childbirth. These are laudable achievements but at a hidden cost he said. “We are being told that all the visibly pregnant mothers in the IDP, camp must be aborted and others sterilised for fear that their babies will become Boko Haram terrorists, since some of them have been raped by the sect. UNFPA’s abortion and sterilisation services are geared towards depopulation,” he posited. “The UNFPA is an organisation whose primary interest is population control. In the developed countries of the world now in their demographic winter, UNFPA’s job is to promote population increase by all means. He further stated that developed countries will do anything to increase their population because they are dying out. Mr Sonnie Ekwuwusi, a director in the organization agreed with Okwuosa'ssentiments stating that the appointment of former Minister of Health, Professor Babatunde Osotimehin as Director General of UNFPA was aimed at making Nigerians and Africa as a whole buy into the idea of depopulation Ekwuwusi however condemned any attempt to subject these pregnant women and girls in the IDPs to a traumatic, violent-wrecking and life-threatening abortion processes. He recommended: “The pregnant girls and women should be offered free ante- natal clinics and rehabilitation centres where they could go to safely give birth to their babies and afterwards they could give them out for legal adoption if for any reason they do not want to keep the babies,”.

Pope Francis says he hasnt watched TV since 1990

The leader of the Roman Catholic Church, who has made waves of connections reaching out to disaffected Catholics and insisting on making the poor a top priority, hasn't watched TV since July 15, 1990, he revealed in an interview published in the Argentinian newspaper La Voz del Pueblo. The pontiff did not reveal why he gave up watching TV, except to say he decided it wasn't for him, before promising the Virgin Mary he wouldn't watch again. That promise has kept him from watching his favorite soccer team, Buenos Aires-based San Lorenzo, but he told the paper a member of his Swiss Guard tells him the scores and keeps him up to date on the standings. Pope Francis said he really misses the tranquility of just walking the streets. The Pope concluded that he would like to be remembered as a "good guy" who tried to do good".

Jonathan deprived EFCC of funds –Lamorde

Chairman of the Economic and Financial Crimes Commission (EFCC), Mr. Ibrahim Lamorde, yesterday indicted the outgoing Jonathan administration, blaming it over the poor performance of the agency. Speaking through the commission’s spokesman, Wilson Uwujaren, the EFCC boss, blamed its inability to tackle corruption on inadequate funding from the outgoing government. According to Uwujaren, “we are happy that the incoming government is making the fight against corruption one of its cardinal objectives. Every Nigerian is happy about that. EFCC has been doing this for more than 11 years. We are proud of what the incoming administration wants to do. “We need an administration that will look at what we are doing and empower us sufficiently to enable us make more impact than we have ever done in the past. We welcome the focus and we believe Nigeria needs to tackle this fight more rigorously for us to make the needed impact.” Uwujaren proudly listed series of achievements recorded by the agency in over 10 years of its existence, claiming significant progress had been made in the prosecution of former governors. He said assets that belonged to some of ex-governors had been seized, while money running into billions of dollars had been recovered on behalf of the Nigerian government. “It is important to recall some of the milestones achieved by the commission in the investigation, prosecution and recovery of assets of politically exposed persons, including ex-governors,” Uwujaren noted. He denied rumours that the EFCC was involvedin corruption in regards to seized assets and frozen accounts of suspects. Sun News

B.B. King was poisoned by his Manager, say his daughters

the reason they said she killed him was because she refused to let them see their Dad when he was gravely sick and then prevented them from taking photos of him when they eventually saw his body. Williams and Patty King - along with sisters Rita Washington and Barbara King Winfree, and brother Willie King - first raised suspicions last week during a viewing of King's body. A week before King's death, a judge in Las Vegas dismissed a request from Williams to take over as King's guardian. An April 29 petition alleged that Toney had blocked King's friends from visiting him and had put her family members on King's payroll. It also alleged that large sums of money had disappeared from King's bank accounts. On Thursday they said that they didn't think their father looked like himself. Their father reportedly died from several stroked caused by his diabetes. Williams and Patty King accused Toney of keeping them from seeing their father for a week after he died May 14 at home at age 89 and of preventing them from taking photos of him in his casket. 'A picture paints 1,000 words,' Patty King said as she showed cellphone images of the same family group with their father at his birthday in September. 'He loved his children.' The five family members refer to themselves as a family board. Three doctors determined that King was appropriately cared-for, and King received 24-hour care and monitoring by medical professionals "up until the time that he peacefully passed away in his sleep," Toney's attorney Brent Bryson said on Monday. "He did not want invasive medical procedures," he said. "He made the decision to return home for hospice care instead of staying in a hospital. These unfounded allegations have caused Mr. King to undergo an autopsy, which is exactly what he didn't want." B.B. King is survived by 11 of his 15 children. Toney said she's doing what B.B. King said he wanted. 'They want to do what they want to do, which is take over, I guess, but that wasn't Mr. King's wishes. Mr. King would be appalled.' B.B. King's will, dated Jan. 18, 2007, and filed Wednesday under his birth name, Riley B. King, appoints Toney as sole executor of his affairs. Another daughter, Riletta Williams, was second in line, but she died last September. Toney is banning the media and photographs of any kind during the public viewing from 3 to 7 p.m. at the Palm Mortuary on South Jones Boulevard. Funeral director Matt Phillips said viewers will be able to file past the open casket and security officials will prevent photos. The media won't be allowed inside. Clark County Coroner John Fudenberg said on Monday that an autopsy was performed on King's embalmed body on Sunday, and that the test results will take up to eight weeks. B.B. King will be buried on May 30 at the B.B. King Museum and Delta Interpretive Center in Indianola. AP.

Catholic Bishops appeal to rescued pregnant women not to consider abortion

Catholic Bishops in Nigeria have appealed to rescued women who are pregnant for Boko Haram members not to consider abortion. The Catholic Bishops, under the aegis "Catholic Bishops Conference of Nigeria, CBCN spoke through the Chairman, Health Committee of the CBCN, Most Reverend Anselm Umoren at a press conference in Abuja today May 25th. The Bishops in their submission, said the life of every baby was distinct from that of the parents. They insisted that aborting such children amounted to visiting the sin of the terrorists, who impregnated the women, on the innocent child.

Gov. Amaechi speaks on his fight with Patience Jonathan and GEJ

Rivers state governor, Rotimi Amaechi says despite the effort by First Lady Patience Jonathan and the president to remove him from office, they are all leaving government at the same time. He said the president and his wife had wanted him to leave office before the end of his tenure but he is now seeing the end of his administration. While speaking at the presentation of a special documentary titled 'The Amaechi Years', the governor said Patience Jonathan interfered with operations of the military apparatus in the state, ordering the transfer of military officers in the state just because they greeted him. "People have asked me why I opposed President Goodluck Jonathan. When the fight started, instead of receiving money from the Federal government, we were sending money to the Federal Government. Have you seen a country where the Commissioner of Police reports to the wife of the President? That is happening in Rivers State. Have you seen a country where a Brigade Commander reports to the wife of the President or where the Navy Commander or Air force Commander reports to the wife of the President? This happened in Rivers State. The wife of the President will come, they will go and wait for her at the airport. She will tell them to come there at 9.00am, she will come by 12noon. They will escort her to her house, she will go upstairs and come down by 9.00pm and they will all be on ground waiting for her. She will say, I heard you greeted Amaechi last week. Why did you greet him? I will transfer you and you are transferred. The more she did that, the more the President turned his back, and the more I fought because I felt that such a system is not a system that will make Nigeria grow. Why I agree with my friends who says forget the past because it is gone, I think it is a lesson. Governance is about the man that has been elected and he has the responsibility to deliver services to the people. There was a time when it was everywhere that the Supreme Court will remove Amaechi. That was on until we defeated them at the Supreme Court. I told the Rivers people to go about their business because I have finished praying and that President Jonathan cannot remove me. We are leaving at the same time. They didn’t want me to stay to the end, but here I am staying till the end.”he said

Pic: Masturbating men ‘will find their hands pregnant in the afterlife’- Muslim televangelist

A Muslim televangelist, Mücahid Cihad Han has set Turkish social media aflame by claiming that a man would meet his masturbating hand 'pregnant in the afterlife' and is 'asking for its rights. Lol Self-styled televangelist Mücahid Cihad Han dived into some delicate matters on May 24 when he answered his viewers’ questions on private television station 2000 TV, Turkish media has reported. Han initially looked puzzled when a viewer said he 'kept masturbating, although he was married, and even during the Umrah,” a pilgrimage to Mecca performed by Muslims which can be undertaken at any time of the year, in contrast to the Hajj. After repeating the question a few times, Han claimed that Islam strictly prohibits masturbation as a “haram” (forbidden) act. “Moreover, one hadith states that those who have sexual intercourse with their hands will find their hands pregnant in the afterlife, complaining against them to God over its rights,” he said, referring to what he claimed to be a saying of Prophet Muhammad. “If our viewer was single, I could recommend he marry, but what can I say now?” the televangelist added, advising the viewer to “resist Satan’s temptations.” Is masturbation forbidden in Islam? “Istimna,” the Arabic term for masturbation that Han also referred to, is a controversial issue in Islam, as there have been varying opinions on its permissibility throughout history. The Quran has no clear reference to masturbation and the authenticity of many hadiths is questionable. Despite Han’s assertive religious stance, only a limited number of Islamic interpretations categorize masturbation as “haram,” while most of others call it a “makruh” (disliked) act. Many of the mainstream Islamic interpretations even allow it in certain conditions, like if the act could be used to avoid the temptation of an extramarital affair. Han, who has more than 12,000 followers on Twitter, was mocked on Turkish social media on May 25, after newspapers published his latest television “fatwa.” “Are there any hand-gynaecologists in the afterlife? Is abortion allowed there?” one Twitter user asked, while mentioning Han’s Twitter user name. “So you think that being pregnant is a God-given punishment?” another user asked.

NASA Discovers New Planet Covered With Marijuana

NASA has announced this morning that they have discovered a planet completely covered with marijuana, a discovery that has completely taken scientists by surprise. Planet X637Z-43, discovered using NASA’s Kepler satellite, would also allegedly be one of the very few planets potentially habitable according to NASA experts, who have detected sufficient levels of oxygen and nitrogen to support human life. The presence of marijuana on other planets could strongly encourage future generations to take interest in space exploration, some experts believe. Scoop has more: “We always think young people aren’t interested by anything but it’s false. Young people love smoking pot,” explains David Charbonneau, astronomer at the Harvard-Smithsonian Center for Astrophysics. “Chlorophyll concentration analyses generated by Kepler lead us to believe that the level of THC in these marijuana plants is 3000% higher than the plants found on Earth. If that doesn’t motivate young people to explore space, I don’t know what will,” admits the expert, clearly enthusiastic. “Regardless, marijuana will without a doubt be a valuable and indispensable resource for interstellar trips. Imagine if it takes 140 years to travel from one planet to another, let’s just say it’s going to be a very long trip. You better have rolled yourself a couple of joints for the road,” he admits with humor. Since the discovery, NASA has launched a campaign on social medias to name the new planet and so far, the name Bob Marley has taken the lead with over 2 094 367 votes at the time of this report.

Civil Servant Attempts Suicide Over Unpaid Salaries

Mr. Ojo Owolabi, a senior civil servant in the Obokun Local Government Area of Osun State, tried to kill himself by drinking a large quantity of insecticide. It was gathered that Owolabi tried to kill himself because his salary hadn’t been paid for the last 6 months, hence was unable to feed his family. According to Punch, the incident which took place last Saturday caused panic in the neighborhood when the news spread that Owolabi had tried to commit suicide. Owolabi, who is a sanitary officer at the council was receiving treatment at a hospital. A source close to Owolabi said he became frustrated because he couldn’t take care of his family. The source said: Baba Ibeji (Owolabi) drank herbicide. He was frustrated because he has been unable to feed himself and other members of his family. You are aware that the state government has not paid workers for some months now. I think he just lost hope and decided to take his life by drinking Gramoxone. Members of his family rushed him to a hospital in Ile Ife, where he was admitted
