An initial review into the deaths of a Royal Marine in Afghanistan has revealed it was not caused by "friendly fire", the Ministry of Defence has said.
27 year-old Corporal David O'Connor was serving with 40 Commando, based in Taunton.
He was killed while on patrol in Helmand Province on Wednesday.
Corporal Channing Day from 3 Medical Regiment was also killed. Both were deployed to Afghanistan last month to help train Afghan National Security Forces.
An Afghan man, who is believed to have been a member of the Afghan Uniformed Police also died during the incident, an MOD spokesperson confirmed.
He added that the deaths were not the result of a "friendly fire" incident but that investigations into who was responsible could take some time.
