Boston terror attacks: Massachusetts jury declares Tsarnev 'guilty' of all 30 charges

A Massachusetts jury has declared Boston terror attack accused Dzhokar Tsarnaev guilty of all 30 charges that he faced, many of which carry death sentence.

The decision was announced on Wednesday, after the jury deliberated for over 12 hours spread over two days, reported the BBC.

As the verdicts were read, Tsarnaev kept his hands folded in front of him and looked down.

The jury will now have to decide if he would face death penalty as the trial enters its second phase on Monday.

While admitting that he carried out the attacks, Tsarnaev's lawyers maintained that he was under the influence of his radicalised brother.

Three people, including an eight-year-old boy, were killed during the attack when two pressure cooker bombs packed with nails, ball bearings and other shrapnel detonated at the second World Marathon Majors series in Boston in April 2013.

More than 260 people were injured, with many losing limbs.

The attacks were the deadliest in the United States since 9/11.

Tsarnaev is an ethnic Chechen. His family moved to the U.S. a decade before the bombings.
