Four British soldiers were killed in a "vehicle incident" yesterday near Gereshk in Helmand province, the Ministry of Defence has announced.
The MoD said that three of the dead, who have not yet been named, were from 1st Battalion The Mercian Regiment, while the fourth soldier was from 1st Battalion The Yorkshire Regiment.
The soldiers were serving as part of a Police Advisory Team. Their next of kin have been informed.
Lieutenant Colonel James Carr-Smith, spokesman for Task Force Helmand, said, "They were part of a team that was travelling to assist in an incident at a nearby checkpoint when they were killed in a vehicle incident. They will be sorely missed and their actions will not be forgotten. We will remember them."
Earlier this week the number of British soldiers killed in Afghanistan since the invasion in 2001 passed 300. Prime Minister David Cameron said it was a moment to "reflect".
