A marine has shot and killed another serviceman as they stood guard at the main gate of a Camp Lejeune, North Carolina, in the second fatal shooting on a US military base within two weeks.







The statement said the guard used an M4 rifle to kill the other guard. Fahy said there were other sentries at the gate at the time of the shooting.

Last week three people were killed at the Fort Hood military base in Texas before the shooter, named by authorities as Specialist Ivan Lopez, shot himself dead. In another attack at Fort Hood in 2009 13 people were killed by Nidal Hasan, an army psychiatrist who had said he was angry about US involvement in Afghanistan and wanted to protect Islamic and Taliban leaders from US troops.
