Boston Marathon bomber Dzhokhar Tsarnaev on Wednesday apologized for the deadly 2013 attack at a hearing at which he was to be formally sentenced to death.
"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," Tsarnaev, 21, told a federal court.
It was the first time that the ethnic Chechen, who did not speak in his own defense during his trial, had addressed the court.
"In case there is any doubt, I am guilty of this attack, along with my brother," Tsarnaev said, standing at the defense table.
Tsarnaev was found guilty of killing three people and injuring 264 in the April 15, 2013, bombing near the finish line of the world-renowned race, as well as fatally shooting a police officer three days later.
