KABUL, Jan. 20 (Xinhua) -- Up to 15 Taliban militants have been killed in separate operations in different Afghan provinces, authorities said Sunday.
"Afghan and coalition forces killed six insurgents, detained one, and located two weapons caches during operations in eastern Afghanistan throughout the past 24 hours," the NATO-led International Security Assistance Force (ISAF) said in a statement.
Afghan Border Police killed six insurgents during an engagement in Achin District in Nangarhar province 120 km east of Kabul, the ISAF's statement said.
The weapons caches were found in eastern Khost and neighboring Paktia province, the ISAF forces said in the statement.
In addition, Afghan army and police launched a cleanup operation on Saturday in the country's Helmand province, 555 km south of Kabul, to clear the militants in areas in Nad Ali and Marjah Districts, killing nine armed Taliban militants, a spokesman for provincial government, Ahmad Zirak, told Xinhua on Sunday.
He said the Afghan army troops also detained a Taliban fighter, who shot dead a teenage girl in Nad Ali District, during the operation.
The Taliban has been waging an insurgency since its regime was toppled by a U.S.-led invasion in late 2001.
