Taliban troops wounded in Afghanistan fighting

Afghan and US troops backed up by American aircraft fought suspected Taliban rebels in southern Afghanistan on Saturday and an unknown number of militants were killed, an Afghan commander said. The fighting occurred in Helmand province's Sangin district, a hotbed of insurgency and the booming drugs trade, said Gen. Rahmatullah Raufi, an Afghan army commander. A US military spokesman said he had no details on the matter. Fighting has spiked in southern Afghanistan in the past year, leaving swaths of it off-limits to aid workers and raising concerns for this country's fragile democracy.
