The surviving suspect in the Boston Marathon bombings has been charged with using a weapon of mass destruction, the US Department of Justice says.
Dzhokhar Tsarnaev, who was charged in hospital, could face the death penalty.
A White House spokesman has said Mr Tsarnaev will not be treated as an "enemy combatant", as suggested by some Republican members of Congress.
The twin bomb attack near the finishing line of the marathon killed three people, and injured more than 200.
He has been unable to speak because of a throat wound, though he has reportedly responded to questions in writing.
