BOSTON (AP) -- Lawyers for Boston Marathon bombing suspect Dzhokhar Tsarnaev (joh-HAHR' tsahr-NEYE'-ehv) are headed to court to ask a judge to ease restrictions placed on him in prison as he awaits trial.

Tsarnaev's lawyers argued in a motion filed last month that so-called ''special administrative measures'' are impairing their ability to defend him. The measures are often used in terrorism cases and restrict access to the mail, the media, the telephone and visitors.

Oral arguments are scheduled Tuesday in U.S. District Court.

Tsarnaev is accused in twin bombings near the finish line of the April 15 marathon. Three people were killed and more than 260 were injured.

Authorities allege that he and his brother, Tamerlan, built and planted the bombs. Tamerlan Tsarnaev died four days after the marathon following a gun battle with police.
