"We have reports that 12 people were killed, including five foreigners," a paramilitary official told Reuters news agency.

A relative and aides to Mehsud, along with Pakistani government and paramilitary officials, said the attack was shortly before 2am (20:45 GMT), and at least three missiles were fired.

Despite protests by Islamabad, attacks by unmanned drones have continued to hit Pakistan's tribal region bordering Afghanistan.
  
The attack came a day after the Pakistani foreign ministry said that the US has been violating international law by launching missile attacks on the region.
