One day after he was sentenced to life in prison for trying to blow up an international flight near Detroit, the so-call “underwear bomber” has appealed.

Umar Farouk Abdulmutallab was sentenced Thursday to four life terms after pleading guilty in October to eight charges, including weapons of mass destruction and conspiracy to commit an act of terrorism.

His appeal notice was filed in federal court in Detroit.

The 25-year-old called the bomb be carried in his underwear a “blessed weapon” to avenge poorly treated Muslims worldwide.

 The bomb didn't fully detonate aboard an Amsterdam-to-Detroit flight on Christmas Day in 2009, but caused a brief fire that burned Abdulmutallab.

He admitted afterward that the attack was inspired by Anwar al-Awlaki, a radical American-born cleric and leading al-Qaida figure killed by a U.S. drone strike last fall.
