Missiles fired by United States drones have struck two vehicles in north-west Pakistan, killing at least 18 men.
The strike took place in Mir Ali village, 25km from Miranshah, the main town in North Waziristan district.
US drone attacks are fairly regular in North and South Waziristan, which are Taliban and al-Qaeda strongholds.
Officials told the BBC that the first drone fired two missiles at a vehicle, missing it narrowly. It was joined by two more drones, which fired six missiles, killing four men who had abandoned the vehicle.
Several minutes later, a group of 14 was killed when a vehicle taking them to the site of the earlier attack was hit by missiles from another drone.
The BBC reports that it was the latest in a growing number of attacks in Waziristan in the last three months. More than 100 have occurred this year.
