Boston Marathon bomber apologises, sentenced to death

Dzhokhar Tsarnaev sentenced to execution for the 2013 Boston Marathon bombings in which three people died.

Boston bomber Dzhokhar Tsarnaev apologised to his victims for the first time at a highly emotional court hearing Wednesday where he was formally sentenced to death for the 2013 attacks.

The US citizen of Chechen descent was sentenced to death on six counts for perpetrating the Marathon bombings, one of the bloodiest assaults on US soil since the September 11, 2001 attacks.
