The lawyers for the suspect in the 2013 Boston Marathon bombings have filed an appeal to have the trial postponed and moved to a different state.
The move was taken hours after a district court rejected a request by lawyers for Dzhokhar Tsarnaev to move the trial from Massachusetts and to delay it by nine months.
Tsarnaev, a naturalized U.S. citizen with roots in the Caucasus, has pleaded not guilty to charges he placed and exploded two bombs in April 2013 with his older brother, Tamerlan, at the marathon's finish line that killed three people and injured more than 260.
If found guilty, Tsarnaev could face the death penalty.
Tamerlan died in a firefight with police several days after the bombings.
Tsarnaev's lawyers say he would not receive a fair trial in the Boston courthouse, which is near the bombing site.
