BOSTON (Reuters) - A federal appeals court on Friday overturned Boston Marathon bomber Dzhokhar Tsarnaev's death sentence for helping carry out the 2013 attack, which killed three people and wounded more than 260 others.

Tsarnaev and his older brother set off a pair of homemade pressure-cooker bombs near the finish line of the world-renowned race, tearing through the packed crowd and causing many people to lose legs.
