Two British troops have been killed by a bomb in Afghanistan, the Ministry of Defence said.
The Royal Marines from 42 Commando Royal Marines were killed by an improvised explosive device yesterday in the Nad-e Ali District of Helmand Province, the MoD said.
Next of kin have been informed.
A spokesman from the MoD said the Marines were on patrol in the Loy Mandeh area when they were killed.
Spokesman for Task Force Helmand, Major Rolf Kurth, said: "It is my sad duty to inform you of the death of two Royal Marines from 42 Commando Royal Marines in the Loy Mandeh area of the Nad-e Ali District of Helmand Province.
"The two Royal Marines were on patrol, disrupting insurgent activity when they were killed by an explosion caused by an IED. Our thoughts and prayers are with their families and friends in their time of grief."
The deaths takes the number of UK military personnel who have died since operations in Afghanistan began in 2001 to 368.
