Taliban fighters attacked part of a US military outpost in the eastern Afghan province of Nangarhar on Monday, officials said, less than a week after targeting a Polish base in a nearby province.
Attacks on Afghan security forces and civilians have also mounted this week
The attack prompted police to shut part of a highway between the provincial capital and Torkham district near the border with Pakistan, a security source said. The base itself had not been penetrated. No casualties had been reported, provincial spokesman Ahmad Zia Abdulzai said.
