At least 31 people were killed and around a dozen injured in three suspected US drone attacks in Pakistan's north-western tribal belt along the Afghan border, local intelligence officials said on Tuesday, DPA reported.
The first attack took place late Monday in North Waziristan, one of the seven tribal districts where Taliban and al-Qaeda have hideouts.
An intelligence official who spoke on condition of anonymity said that a US drone fired two missiles into a vehicle in the Datta Khel area, killing five people.
"Later the drone fired eight missiles into a compound in the same area," the official said. "The attack demolished the building and locals have pulled out 20 dead bodies and 10 injured people from the debris of the house."
"All 10 injured are in critical condition, so we fear that the death toll might rise," he added.
Early Tuesday, another airstrike took place in the adjoining district of South Waziristan.
"A US drone fired two missiles into a vehicle. Six people died in the attack," said a second intelligence official who also sought anonymity.
The identities of those killed in the three attacks were not known yet.
