ISLAMABAD, Pakistan (CNN) -- Two missiles believed to be fired by a U.S. unmanned aircraft on Saturday killed three militants in Pakistan's tribal region, a Pakistani intelligence official told CNN.
The incident took place in the Sidgi village in North Waziristan, according to the official, who asked to remain anonymous because he was not authorized to speak to the media.
The official said the drone strike target was a house.
The United States offers no comment on reported drone attacks. However, the United States is the only country operating in the region known to have the ability to launch missiles from drones, which are controlled remotely.
The incident occurred as a Shiite Muslim procession ahead of the holy day of Ashura on Sunday was expected to pass through that area, police said.
