Suspected US spy drones fired missiles early Thursday into a restive Pakistani tribal area on the border with Afghanistan, killing four people, security officials said.
The missiles hit a madrassa, or an Islamic religious school, in a village just outside Miranshah, the main town in North Waziristan, residents and officials said.
"At 2:25 am, two spy drones fired three missiles at the madrassa of Mullah Mansoor. Three people were killed immediately, four were injured and another later expired at hospital," a security official told AFP.
