Umar Farouk Abdulmutallab, the Nigerian national accused of attempting to bomb a United States bound flight on Christmas Day 2009, has changed his plea to guilty.

Abdulmutallab is presently on trail in Detroit after attempting to sneak plastic explosives - hidden in his underwear - onto Northwest Airlines Flight 253 in Amsterdam.

The flight was en route to Detroit, Michigan.

His lawyer told the second day of the trail that the 24-year-old would admit terrorism and other charges.

In the bungled attack, Abdulmutallab caught fire when a bomb sewn into his underwear failed to detonate fully.

If convicted, he faces a lifelong prison sentence.

Following the attack Abdulmutallab claimed he was ”one of many” bombers preparing to attack the United States prompting a global security crackdown.
