US-led coalition and Afghan forces raided several homes in a district just north of the capital, killing several militants who shot at them, the coalition said Saturday. The operation in the Tagab Valley of Kapisa province, 40 miles (65 kilometers) northeast of Kabul, targeted a militant leader, a coalition statement said. During the operation, militants fired on the Afghan and U.S. forces from covered defensive positions. A separate militant group attacked the joint forces from another building, prompting the US and Afghan soldiers to respond with gunfire and an airstrike, killing the militants. The coalition did not say how many militants were killed. In the south, armed gunmen killed a tribal leader in a district north of Kandahar city.
