Pakistani intelligence officials say a missile fired by an unmanned aircraft has killed at least 12 people in northwest Pakistan.
All such attacks by drone aircraft are believed to be carried out by U.S. forces.
Saturday's missile strike, aimed at a compound in the village of Issori in North Waziristan, is the first known to have taken place since the start of monsoon floods that have battered much of the country.
During President Barack Obama's administration there has been an increase in such remote-controlled air strikes against suspected al-Qaida and Taliban hideouts near Pakistan's border with Afghanistan.
Pakistan's government has protested against the attacks as a violation of its sovereignty.
