A jury has sentenced U.S. army psychiatrist Nidal Hasan to death for killing 13 people during the 2009 shooting rampage at Fort Hood in Texas.


The U.S.-born Muslim said the attack on unarmed soldiers was motivated by a desire to protect insurgents fighting in Iraq and Afghanistan.


He offered no defence in his trial.


The same jury that sentenced him to death Wednesday found him guilty last week in the attack, which also wounded more than 30 people.


Before an execution date is set, the sentence will face years of appeals.
