At least eight people were killed and two others injured in a U.S. drone strike launched Monday afternoon in Pakistan's northwest tribal area of North Waziristan, reported local media.

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.

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.

Located along the Pakistan-Afghanistan border area, North Waziristan is considered to be a major stronghold of militants in the country.

Despite the fact that the U.S. drone strike is mainly targeting at the militants active in the area, many innocent people have also been mistakenly killed in such strikes and this has led to a strong resentment against the United States among the local people.

Analysts here believe that with the step-up of the U.S. drone strikes against the militants in Pakistan, more retaliatory actions will also be taken by the militants in the country in the near future.
