More of the survivors of the Boston Marathon bombings have said that justice has prevailed, after convicted killer Dzhokhar Tsarnaev was sentenced to die by lethal injection for his part in the 2013 attack.

A jury in Massachusetts returned the unanimous decision after 14 hours of deliberation.

Tsarnaev, 21, was convicted of all 30 counts relating to the attacks on 15 April 2013, which killed three and injured 264 others.

Following the sentencing, survivors and witnesses of the attack and its aftermath continued to talk about their relief.

"Now he will go away and we will be able to move on. Justice. In his own words, 'an eye for an eye'," said Sydney Corcoran, who nearly bled to death in the attack and whose mother lost both legs.

Liz Norden has two adult sons who each lost a leg in the attacks. "I feel justice for my kids," she said. "It feels like a weight has been lifted off my shoulders."

Meanwhile another amputee, ballroom dancer Adrianne Haslet-Davis, tweeted: "My heart is with our entire survivor community. I am thrilled with the verdict!"

However, opinion polls indicated that Massachusetts' residents would have preferred a life sentence for Tsarnaev. The state outlawed the death penalty back in 1947 andTsarnaev was sentenced under

The state outlawed the death penalty in 1947 and Tsarnaev was sentenced under federal law.

Some survivors have opposed his death sentence. Bill and Denise Richard were the parents of eight year-old Martin, who died in the attack.

They have publicly called for Tsarnaev to be given a life sentence, so that their family be spared years of legal appeals by the bomber.

Meanwhile, another survivor, Laurie Scher, said that the trial had "been healing" and that Tsarnaev's death sentence brought her "no" relief.

"I have my personal feelings about that and I'd like to keep them to myself," she said.
