At least eight Daesh insurgents were killed in two separate airstrikes by the foreign troops in Afghanistan\u2019s eastern Nangarhar province, the local officials said on Thursday. The airstrikes were conducted in Achin and Nazyaan districts of the province yesterday. Attaullah Khoghyani, a spokesman for the provincial governor, said three other insurgents were injured in addition. "The first attack took place in Achin after foreign troops targeted safe havens belonging to insurgents. Six Daesh insurgents were killed and three were injured. Two other Daesh insurgents were killed in another airstrike in Nazyaan," Tolo News quoted Khoghyani as saying. He, however, did not provide further details about the strikes. The strikes comes after the U.S military this week announced that it is adding troops in eastern Afghanistan for offensives against Daesh. Reports suggest that the head of the U.S-led Resolute Support mission in Afghanistan, General John Nicholson, is making use of a special authority given to him by U.S. President Barack Obama. Meanwhile, the Afghan security forces commander in the east, General Mohammad Zaman Waziri, said the next phase to clear the area will involve a deployment of Afghan ground forces with close air support provided by the U.S and Afghan air forces.
