US prosecutors will seek the death penalty for Boston Marathan bombing suspect Dzhokhar Tsarnaev, Attorney General Eric Holder said in a statement today.

"The nature of the conduct at issue and the resultant harm compel this decision," Holder said.

Prosecutors say that Tsarnaev, 20, and his brother Tamerlan, 26, planted a pair of homemade pressure-cooker bombs at the race's crowded finish line on 15th April 2013, killing three people and wounding 264.

Three nights later, the pair killed a university police officer and later engaged in a shootout with police that left Tamerlan dead, it is alleged.
