http://news.bbc.co.uk/2/hi/in_depth/3651202.stmUS forces have killed 22 suspected Taleban and al-Qaeda militants in a gun battle in southern Afghanistan, the US military says.
American troops and helicopters fought the insurgents in the Shinkay district of Zabul province, late on Sunday.
"Twenty-two anti-coalition militias were killed - three of them were Arabs," US military spokesman Major Scott Nelson said in Kabul.
Zabul province is widely regarded as a Taleban stronghold.
He said about 40 militants armed with AK-47s and rocket-propelled grenades had attacked American troops on patrol.
"Our soldiers were out doing a cordon search when they were engaged by a large force of anti-coalition militias," Major Nelson said.
