A US pilotless aircraft fired a missile into Pakistan"s North Waziristan tribal district Friday, killing three suspected Taliban insurgents, dpa quoted an intelligence official as saying. The missile strike targeted a vehicle near Mir Ali, a major town in the region that borders Afghanistan. "According to initial reports, the attack destroyed the car and killed three people," an intelligence official said on condition of anonymity. The official said it was not immediately clear whether any more people were travelling in the vehicle. The Friday morning attack was the second in North Waziristan in as many days. Five people were killed and at least two more injured when two missiles believed to be fired from a US drone struck the house of a Taliban sympathizer in the Machikhel area Thursday night. The identities of those killed in the two strikes were not known, the official said.
