Four NATO troops killed in Afghanistan

Four service members have been killed in an insurgent attack in western Afghanistan, Nato said today.

An alliance statement said the troops died today.

It did not provide nationalities or specify where the attack occurred.

The deaths brought to 24 the number of Nato forces killed this month. At least 2,012 Nato service members have died since US-backed forces toppled the Taliban regime in 2001, according to an Associated Press count.
