'Four ISAF service members were killed as a result of improvised explosive device (IED) strikes from insurgents that occurred on July 11 in southern Afghanistan,' the release said.
However, it did not mention the nationality of the victims and the exact place of the incident, but added another service member succumbed to wounds received in a combat in Afghanistan last month.
The coalition forces have launched a major offensive against the insurgents in the southern Hemland province since July 2, forcing the militants to expand their activities in the northern provinces.
