A Royal Marine and a woman soldier have died from injuries received while on patrol in Afghanistan.
The Royal Marine, from 40 Commando who are based at Norton Manor Camp near Taunton, and the soldier, from 3 Medical Regiment, were on patrol in the Nahr-e Saraj district of Helmand Province when they were killed on Tuesday.
Their families have been informed.
The soldier is said to be a 25-year-old woman from Northern Ireland.
The pair are thought to have been killed by insurgents, although a source has said it understood the Taliban had issued a statement in Afghanistan suggesting the incident was a 'green on blue attack' - where coalition troops are killed by their Afghan allies.
Their deaths take the total number of UK service members to have died since operations in Afghanistan began in October 2001 to 435.
