Question: PORT HARCOURT, Nigeria (CNN)  -- Trash litters its cities. Electricity is sporadic at best. There is no clean water. Medical and educational services are limited. Basic infrastructure is severely lacking. "Planet in Peril" met in a secret location with members of the Movement for the Emancipation of the Niger Delta. These are not conditions that should plague one of the richest oil states in the world. Hundreds of billions of dollars has been made from the Niger Delta's oil reserves and many people have gotten very rich. Conversely, the average Nigerian has suffered as a result of the country's oil prosperity. The United States Agency for International Development says more than 70 percent of the country lives on less than a dollar a day -- the population is among the 20 poorest in the world. Oil companies are only part of the equation. The other is the Nigerian government. Transparency International, a global organization intent on stamping out corruption, has consistently rated Nigeria's government one of the most corrupt in the world. Nigeria's federal government and oil companies split oil profits roughly 60-40. The money is then supposed to make its way down to the local governments to fund various projects. Somehow, little money actually reaches its intended destination. Nigeria's own corruption agency estimates between $300 billion to $400 billion has been stolen or wasted over the last 50 years.  Lisa Ling travels to secret location to meet notorious Nigerian militant group » . Gov. Rotimi Amaechi of Rivers state, one of the largest oil producers of Nigeria's 36 states, acknowledges past problems with corruption, but thinks progress is being made. "There's a lot of improvement," Amaechi said. "The work being done by the corruption agency and the federal government has somehow been able to control the level of corruption in government." Over the last few years, a culture of militancy and violence has arisen in the absence of jobs and services. Kidnappings for ransom, robberies and even murder happen with regularity. The biggest and most powerful armed group is the Movement for the Emancipation of the Niger Delta, or MEND. They say they are at war against the Nigerian military and the oil companies operating there. MEND, formed in 2005, said it has more than 30 camps throughout Nigeria. Members are armed with high-tech weaponry they said was obtained from "foreign sources." Hundreds of people have been killed on both sides and countless oil workers have been kidnapped. Over the years, MEND's attacks on oil pipelines have halted oil production and, therefore, raised the price of oil around the world. They demand oil profits be distributed to average Nigerians of the Niger Delta and said they will not stop their attacks until their objectives have been fulfilled.  See environmental battle lines for "Planet in Peril" » . The battle is over oil -- one of the world's most valuable resources. But to most Nigerians -- oil is a curse. It has provoked an environmental disaster of monstrous proportions. Since the 1970s, the United Nations estimates there have been more than 6,000 oil spills in the Niger Delta -- that is equal to more than 10 times the amount spilled from the Exxon Valdez in 1989. Yet, there is no international outcry and rarely are the spills reported, even to most Nigerians. They are still happening and the consequences are nothing short of devastating. Communities along the Niger Delta have lived off subsistence fishing and agriculture for decades. Collecting food becomes impossible when a spill happens, like one that occurred in August. The waterways and mangroves are blanketed in thick brown oil sludge that goes on for miles. Toxicity overpowers the air and a sense of lifelessness pervades the landscape. Many say it will take 10-15 years for the area to be free of contamination -- if the cleanup effort commences in a timely manner. The August spill was a result of a leak from an old pipeline that had corroded. It took the oil company three months to clamp the leak, but the company said it wasn't reported for a full month after it began. Once the leak was reported, the company said it was denied access to the site by the community. Leaders of the village deny that, and the finger-pointing between the two sides is nothing new -- there is no love lost here.  Who is telling the truth? Who knows? Either way, the creeks are blackened. This is life in the Niger Delta.

Question: London (CNN) -- London's Heathrow Airport is "fully operational" and returning to normal after an emergency landing Friday forced the closing of both runways, the airport said -- but many travelers are likely to suffer delays anyway. British Airways has canceled all its inbound and outbound short-haul flights until 4 p.m. (11 a.m. ET) as a result of the incident. And Heathrow Airport has warned of disruption to travel that could last all day. So far, 23 planes have been diverted to other airports and 19 flights canceled, some arrivals and some departures, a spokeswoman said Friday morning. The airport is working to return to normal service as soon as possible, she said, but passengers are advised to check with their airlines. A British Airways plane bound for Oslo was forced to make the emergency landing "due to a technical fault," the airline said. Flight BA762 turned back less than half an hour after taking off for the Norwegian capital, it said. The Airbus A319 aircraft was carrying 75 passengers and five crew members, the airline said. The passengers were evacuated from the plane on emergency slides. "Airline colleagues are now caring for customers in the airport terminal," said British Airways. London Ambulance Service treated three patients for minor injuries after the emergency landing, it said on Twitter. British Airways said it would be carrying out a full investigation into the incident, alongside the Air Accident Investigation Branch, part of the UK Department for Transport. The slides were deployed on the left side of the aircraft, indicating that the problem was with the right engine, said CNN's Richard Quest. Planes can fly safely even if only one engine is operational, he said. London Fire Brigade said one of its crews helped the airport fire service put out an aircraft fire. "We believe the fire is now out," it said via Twitter. Heathrow, which is a major international hub, was ranked the third busiest airport in the world in 2012 after Atlanta and Beijing, according to Airports Council International. Monday is a holiday in the United Kingdom, so many people will be taking flights Friday to take advantage of the long weekend. Holidaymaker Aileen Wilson was one of many travelers whose flight was grounded by the incident. "We've just been sitting, waiting in a plane meant to take off" this morning, she told CNN iReport. "At first we were told ongoing incident and then emergency landing. We (are) still waiting to take off (and) not allowed out of plane!" Instagram user Shazia Shaikh took a photograph from the office where she works at Heathrow Airport of emergency vehicles surrounding a plane. "Runways closed (and) lots of smoke," she told CNN iReport. "The rain doesn't help. Emergency vehicles were quick to the aircraft I'm told." On average, 190,000 passengers travel through the airport each day, half arriving and half departing, according to Heathrow's website. CNN's Claudia Rebaza, Richard Allen Greene, Sarah Brown and Dominique Van Heerden contributed to this report.

Question: Kenyan counterterrorism sources are looking at a Norwegian citizen of Somali descent as a possible suspect in the Westgate mall attack last month, the sources told CNN on Friday. The Norwegian citizen is believed to have ties to Mohamed Abdikadir Mohamed, known as Ikrima, who is regarded as one of the most dangerous commanders in the Somali terror group Al-Shabaab. Norwegian intelligence services are in Kenya investigating Ikrima and the Norwegian citizen, the Kenyan sources said, and have also spoken to the latter's sister in Norway. Norwegian authorities have not yet released the Norwegian citizen's name. Kenyan authorities suspect Ikrima of involvement with the Westgate mall attack. Al-Shabaab claimed responsibility for the bloody four-day siege at the upscale mall in Nairobi, where at least 67 people died. U.S. officials said Ikrima was the target of a raid earlier this month by U.S. Navy SEALs on an Al-Shabaab compound near the town of Baraawe in Somalia. It's believed that he escaped after the U.S. troops came under heavy fire. A Kenyan intelligence dossier seen by CNN alleges Ikrima's involvement with Briton Samantha Lewthwaite, a terror suspect known as the "White Widow," in a foiled Mombasa attack in 2011 with Jermaine Grant, a fellow British citizen currently held in Mombasa on terror charges. Kenyan intelligence sources say that Ikrima, who speaks six languages and grew up in Kenya, is the main "point person" between al Qaeda in Somalia and al Qaeda in the Arabian Peninsula, and that he has helped pinpoint Kenyan targets. Recruiting operatives in the West? Morten Storm, a former informant who has worked for several Western intelligence agencies, has told CNN that he developed a close relationship with an Al-Shabaab figure called Ikrima between 2008 and 2012. He said he is confident that it's the same person who was targeted by U.S. forces. Inside story on an Al-Shabaab commander . Storm, who is Danish, described Ikrima as a Somali-Kenyan Al-Shabaab operative who had spent time in Norway. He said that Ikrima made clear to him via e-mail that he was ready to send recruits from the West back home from Somalia to launch attacks. Norwegian journalist Bent Skjaerstad told CNN his sources have confirmed that Ikrima had indeed spent time in Norway and had tried to recruit for Al-Shabaab in Europe. Skjaerstad, who reports on security and terrorism for TV2, said Ikrima had lived there between 2004 and 2008. He had failed to gain asylum status but had been given Norwegian travel papers. Skjaerstad told CNN that according to his sources, Ikrima had traveled to Somalia while living in Norway and had used about a dozen aliases. Friends of Ikrima who knew him from his time growing up on the Nairobi suburb of Eastleigh told CNN he traveled to Norway in 2003 and grew increasingly radicalized there. The sources, who had kept up with him over the years, said Ikrima traveled in 2007 to London, where they lost contact with him. In 2008 they heard that he was in Somalia, where he has been based since. Arabic is among the six languages spoken by Ikrima, and he studied French for two years at the Alliance Francais in Nairobi, his friends say. Al-Shabaab in Norway . The possible involvement of the Norwegian citizen in the Westgate mall attack has highlighted concerns about the widening reach of the Al-Shabaab group outside Somali borders. Stig Hansen, a security expert based in Norway and author of the book "Al-Shabaab in Somalia," told CNN that if the Norwegian suspect is who he believes him to be, he lived in a small town in Norway but had connections with a wider group, not all of Somali origin. He came to Norway at age 8 or 9 and stayed for a couple of years, during which time he gained Norwegian citizenship, Hansen said. He later returned to Somalia. Al-Shabaab became quite popular among some Somali community groups in Norway from 2007 to 2009, Hansen said, "because they were wrongly seen as some kind of national resistance group." Observers noticed contradictions between what the group said in its English- and Arabic-language messaging, he said, which contributed to ignorance within the diaspora about its real nature. "But the terrorist attacks inside of Somalia made it easier for the wider ethnic Somali community to see that this was really a terrorist organization, and it distanced itself," he said, making it less popular now. However, this development brought its own problems, Hansen said, and not just in Norway. "What you have to look out for, also in the United States and the United Kingdom and all these other Scandinavian countries, are these small, small networks that are in one sense detached also from the Somali community leaders -- radicalized groups of youths and radical preachers, sheikhs, that go traveling around the various countries to try to incite," he said. "That's what we have to watch these days."
