Two missiles fired from a suspected US drone aircraft have killed at least 10 militants in north-west Pakistan, local officials said.
The missiles hit a home in a village in the tribal district of North Waziristan, which borders Afghanistan.
It comes after a man arrested for planting a bomb in New York said he was trained in bomb-making in Waziristan.
The US has launched repeated missile strikes against Taleban and al-Qaeda militants in the region.
Hundreds of people have been killed in such airstrikes in the last two years.
Pakistan has publicly criticised the drone attacks, saying they fuel support for militants, but observers say the authorities privately condone the strikes.
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.
Pakistani officials also said on Sunday that army helicopters had killed at least eight militants in Orakzai tribal region, which borders North Waziristan.
