A suspected drone aircraft on Tuesday fired two missiles at a car in north-western Pakistan, killing at least four people, an official said. The attack took place in the area of Kutab Khel, some five kilometres east of Miranshah, the main city in the district of North Waziristan, near the Afghan border. "According to the initial reports there were five people in the car," the official was quoted as saying by the German Press Agency "DPA" "Three of them died on the spot while one succumbed to his injuries at the hospital. One more is in critical condition," he said.
