At least seven militants died when missiles fired by a suspected US drone aircraft hit a house in north-western Pakistan, security officials said.
The missiles struck a militant hideout in Shawal district in the North Waziristan region on the Afghan border.
The area, a stronghold of the Taliban and al-Qaeda, has been repeatedly hit by similar attacks.
The attacks have killed more than 700 people since January 2009 and fuelled anti-American sentiment in Pakistan.
Pakistan publicly objects to the strikes but analysts believe they have the private backing of officials.
The American military does not routinely confirm drone operations, but analysts say the US is the only force capable of deploying such aircraft in the region.
