A U.S. drone aircraft fired two missiles into Pakistan's North Waziristan region on the Afghan border on Wednesday, killing at least three militants, Pakistani intelligence officials and residents said.

The strike targeted a stronghold of the Haqqani network, a major Taliban faction attacking Western forces across the border in Afghanistan. A similar strike last week in the same area killed a son of Jalaluddin Haqqani, the leader of the group.
