International and Afghan troops killed 11 militants when a raid in Afghanistan's volatile south turned into a gunbattle with Taliban fighters, US forces said Friday. Fighting broke out during the Thursday night raid targeting a key Taliban insurgent in a village in Helmand province, the military said in a statement. The forces came under fire from militants inside a compound as they advanced and returned fire. One insurgent was captured and 11 killed in the fighting in Lashkar Gar district, west of the provincial capital of Kandahar. .
