Convicted Boston Marathon bomber Dzhokhar Tsarnaev has given his first public statement since carrying out the April 2013 terrorist attack.

“I would like to now apologize to the victims, to the survivors,” he told a Boston court shortly before being formally sentenced to death for the bombing.

“I am sorry for the lives I have taken, for the suffering that I have caused you, for the damage I have done, irreparable damage.”

He added: “In case there is any doubt, I am guilty of this attack, along with my brother,” Tsarnaev said, standing at the defense table.

To the victims attending the hearing at the US District Court, he said: “I pray for your relief, for your healing.”
