Sniper suspect John Allen Muhammad has made his first appearance in a Virginia court at the start of a process which could lead to his execution if found guilty. Muhammad, 41, faces murder and terrorism charges in connection with the three-week shooting spree around the US capital last month which left 10 people dead and three wounded. In another court in Virginia, Mr Muhammad's alleged accomplice - 17-year-old John Lee Malvo was remanded in custody in his first hearing since being handed over to state authorities from government custody. The two suspects will face separate trials for different murders.
