The soldiers were killed as a result of an explosion which occurred in an area approximately 20km north of Musa Qal'ah district centre, Helmand province, yesterday afternoon.
Spokesman for Task Force Helmand, Lieutenant Colonel David Wakefield, said:
"It is with deep sadness I must inform you that a single IED explosion yesterday afternoon killed two British soldiers, both from 1st Battalion The Royal Anglian Regiment, serving as part of the Household Cavalry Regiment Battle Group.
"The soldiers were approximately 20 kilometres to the north of Musa Qal'ah district centre and were part of an ongoing operation to clear insurgents from an area where, until recently, the insurgents had held sway.
"Their determined courage in the face of the danger from IEDs and the sacrifice they have made will not be forgotten."
Next of kin have been informed and have asked for a period of grace before further details are released.
These deaths were not associated with Operation MOSHTARAK.
