A prosecutor has told the court that Boston terror attack accused Dzhokar Tsarnaev "wanted to punish America for what it was doing to his people" when he planted bombs at the second World Marathon Majors series in 2013.
While admitting that he carried out the attacks, Tsarnaev's lawyers argued that he was under the influence of his radicalised brother, reported the BBC.
The jury is set to begin their deliberations on Tuesday, after both sides finish their closing arguments.
If found guilty, the 21-year-old who has been charged on 30 counts, will be jailed for life or executed.
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 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.
