One US drone strike in Kunar Province killed one suspected militant commander, whilst on Saturday two more strikes killed four suspected fighters in Laghman province.
Meanwhile, two more US missiles fired from drones on Sunday at the Datta Khel area also injured two.
It is thought the strikes had targetted a compound used by a senior Pakistan Taliban commander.
No reports of civilian casualties or confirmation of the drone strikes from Nato or the Taliban. Reports based on unnamed Pakistani intelligence official.
