Boston Marathon bomber Dzhokhar Tsarnaev has been ordered to pay $101 million in restitution to the victims of his crimes.

The payment is due "forthwith".

The restitution order came down today from Judge George O'Toole, who heard the case in early 2015.

Tsarnaev faces the death penalty after a jury found him guilty and later sentenced him to death.

Any fines associated with the case have been waived.

Judge O'Toole also denied Tsarnaev's request for a new trial.

Three people were killed and more than 260 others were injured when twin bombs placed near the marathon finish line exploded on April 15, 2013. Tsarnaev was convicted of 30 federal charges and sentenced to death for his role in the attack.

Tsarnaev, 22, is being held at the federal Supermax prison in Colorado.
