Four soldiers with the NATO-led International Security Assistance Force (ISAF) were killed on Monday in Improvised Explosive Device (IED) blast in Afghanistan's restive southern region, the military alliance said on Tuesday.
However, the brief statement released by ISAF here did not reveal the nationalities of the victims, saying it is ISAF policy to defer casualty
identification procedures to the relevant national authorities.
Troops mainly from U.S., Britain, Canada and Australia have been stationed in the southern region within the framework of ISAF to fight Taliban militants there.
The southern Afghan provinces, the hotbed of Taliban, have been experiencing increasing militancy over the past couples of years despite
continued military operations since mid last year.
Over 170 NATO soldiers, most of them Americans, have been killed in Afghanistan since beginning this year.
