Dhzokhar Tsarnaev was charged by federal prosecutors Monday in his hospital room with using a weapon of mass destruction to kill - a crime that carries a possible death sentence. Dhzokhar and his older brother Tameran were accused of setting off the twin explosions at last week’s Boston Marathon that killed three people and wounded more than 180. His brother died last Friday in a shootout with the police. Dzhokhar, 19, remains in serious but stable condition unable to speak because of a gunshot to the throat. He is to be prosecuted in a federal court - not tried as an enemy combatant.

US media repored earlier that he had regained consciousness Sunday night and was responding in writing to authorities’ questions.
