'Underwear Bomber' Sentenced To Life In Jail

A Nigerian student who confessed to trying to blow up a US passenger plane headed for Detroit using explosives concealed in his underwear has been jailed for life.

A bomb hidden in the underwear of Umar Farouk Abdulmutallab, now 25, caused a fire but failed to explode on a Delta Airlines flight carrying 289 people on Christmas Day 2009.

Abdulmutallab was eventually overpowered by passengers and crew on the Northwest Airlines flight 253 from Amsterdam to Detroit.

The attack caused the US to tighten up both its 'no-fly' lists and airport security.

The would-be suicide bomber said he was carrying out the work of God against the "oppressors" of Muslims.

He said: "The mujahadeen are proud to kill in the name of God and that is exactly what God told us to do in the Koran."

The US judge gave the maximum sentence, saying: "This was an act of terrorism that cannot be quibbled with."

Abdulmutallab, who pleaded guilty, said his plan was to avenge "the attacks of the United States on Muslims."

The Nigerian became radicalised during a series of trips to Yemen where he met the cleric Anwar al Awlaki, part of al Qaeda's Yemen-based wing.

He travelled to Yemen in 2004 where he enrolled at the Sanaa Institute for Arabic Language.

A former teacher said Abdulmutallab was not deeply religious when he arrived in Yemen in 2004 but became a devoted follower of Islam.

Abdulmutallab stayed in Yemen for a year between 2004 to 2005, before returning for another stay from August 4 to September 21 in 2009.

He claimed he stayed with al Awlaki and spent two weeks preparing at a training camp where he "received instruction in weapons and indoctrination in jihad".
