At least eight people were killed and two others injured in a U.S. drone strike launched Monday afternoon in North Waziristan, a private TV reported. According to the report, the U.S. drones fired four missiles in the area of Tehsil Shawa in Miranshah of North Waziristan which borders Afghanistan and one of the missiles reportedly hit a vehicle carrying five local welfare workers and all of them were said to be killed. There are also reports saying at least four foreign militants belonging to Hafiz Gulbahbdur group were killed in the strike. On the other hand security officials said, four militants were killed in a US drone strike in North Waziristan on Monday. A drone fired three missiles at Darazinda village, 40 kilometres (25 miles) northeast of Miranshah, the main town in North Waziristan region, they said. "The drone fired one missile on two militants riding on a motorbike and when two of their colleagues rushed towards them, two more missiles were fired," a security official told AFP. "All four militants were killed." Two other security officials confirmed the casualties, saying the missiles were fired by the pilotless aircraft. Monday's strike is the second of its kind over the last 24 hours. On Sunday night, the U.S. drone fired three missiles targeting at a house and a car in the Datta Khel area of North Waziristan, killing six Hafiz Gulbahbdur militants. Over 1,100 people have been killed in more than 130 drone strikes in Pakistan since August 2008. However, the attacks fuel anti-American sentiment in the conservative Muslim country.
