BOSTON (AP) — A federal jury in Boston has begun deliberating the punishment for convicted Boston Marathon bomber Dzhokhar Tsarnaev.

Tsarnaev faces either life in prison or the death penalty for the April 2013 attack that killed three people and wounded 260 others. Prosecutors said in closing arguments Wednesday that Tsarnaev wanted to inflict pain and death as a political statement against U.S. wars in Muslim countries.

The defense said Tsarnaev's older brother led him down the path to terrorism.
