US planes pounded several areas in Afghanistan's eastern province of Kunar on Sunday after one of its bases came under rocket attack, officials said.
The pre-dawn raid caused only minor damage to several mud-built houses at the foot of mountains in Narang district, but there were no casualties, villagers said.
Several other bombs were dropped on a location nearby from where militants are suspected to have fired at least two rockets on a US-led military base near a river bed, officials said.
It was not immediately known if the rockets had caused any damage or casualties.
Officials blamed remnants of Taleban and their militant allies loyal to al Qaeda and Gulbuddin Hekmatyar, leader of an Islamic party, for firing the rockets.
