KABUL (AP) - NATO says four American service members have been killed in a roadside bombing in western Afghanistan.
The deaths bring the number of Western forces killed in Afghanistan in August to at least 15, a pace that could make the month the deadliest for the U.S. and NATO in the nearly eight-year war.
Casualties among Afghans and international troops are climbing sharply as Western forces push into Taliban territory ahead of Aug. 20 presidential elections. Most violence takes place in the south and east, the traditional bases of the ethnic Pashtun insurgents. But the Taliban has also been ramping up attacks in the relatively calmer west and north.
