MIRANSHAH (Agencies) A missile strike from a US drone aircraft killed three suspected militants in North Waziristan early Tuesday, security and intelligence officials said. The strike in the North Waziristan region was the first since US President Barack Obamas speech last week outlining plans to send 30,000 more US troops to Afghanistan. The attack targeted a car in Aspalga village, about 12 kilometres southeast of Miranshah, the main town of the restive North Waziristan tribal district bordering Afghanistan, officials said. The three people killed in the attack were militants but as yet their identity is not confirmed, an intelligence official told AFP. The moment the car left a house, it was hit by two missiles. One security official and another intelligence official in Peshawar also confirmed the strike, saying the missiles were fired from an unmanned US aircraft. Three people were also injured in the attack, officials said. The US drones have carried out scores of missile strikes in Pakistan over the past year. In neighbouring South Waziristan, the army has launched a major offensive against the militants in mid-October.
