The Nigerian man who tried to blow up a Detroit-bound airliner with explosives concealed in his underwear on Christmas Day in 2009 has been sentenced to life in prison by a federal judge who said that his crime and subsequent lack of remorse demanded the maximum possible punishment

The African, Umar Farouk Abdulmutallab, who pleaded guilty in October 2011 and admitted to working on behalf of Al Qaeda, shouted, “Allahu akbar,” or “God is great,” five times during the sentencing hearing. He said that Muslims were proud to kill in the name of God, and that is what God told them to do in the Koran.
