A British service man with the NATO- led International Security Assistance Force (ISAF) was killed in an IED (improvised explosive device) strike Monday in southern Afghanistan.

A press release issued Tuesday by the ISAF confirmed the casualty but failed to disclose details.

Thousands of ISAF troops, most of whom are from the United States and the United Kingdom, along side with a large number of Afghan soldiers are to launch a major operation on the Taliban insurgent group in Southern Afghanistan's Helmand province.
