Lawyers for the Boston Marathon bomber Dzhokhar Tsarnaev have filed a notice of appeal over his conviction and the death sentence against him.

The notice filed on January 29 with the 1st U.S. Circuit Court of Appeals does not give any grounds for appeal. Those are to be described later.

Earlier in January, a judge denied Tsarnaev's bid for a new trial.

The 22-year-old Tsarnaev was convicted in 2015 and sentenced to death for the bombings, which killed three people and injured more than 260 in April 2013.

Tsarnaev's lawyers say they are appealing his conviction and sentence and the trial judge's denial of a request to publicly release the jurors' names.
