Pakistani intelligence officials say a suspected U.S. missile strike has killed at least nine people, including foreigners, along the Afghan border.
The officials say an unmanned aircraft launched Friday's attack on the home of an Afghan in North Waziristan in the village of Mohammed Khel.
Pakistani media say at least 20 people were killed, but the military has not confirmed the reports.
Intelligence officials say in a separate attack in North Waziristan Friday, suspected U.S. fighter jets killed two women and a child.
Pakistan's army spokesman, Major General Athar Abbas, denied the incident took place in Pakistan, saying international troops were carrying out an operation in Afghanistan.
Pakistan objects to cross-border attacks and is conducting its own offensive against suspected al-Qaida and Taliban militants in its northwestern Bajaur tribal region.
Amnesty International says Pakistan's military offensive has displaced more than 250,000 people. The human rights group says more than 20,000 people have fled from Pakistan to eastern Afghanistan to avoid the fighting.
The White House announced Friday that Pakistan, Afghanistan and Georgia will receive more than eight million dollars in emergency aid to cope with urgent refugee needs.
