Pakistan drone attack kills a dozen in South Waziristan
A US drone attack has killed at least 12 suspected militants in Pakistan's tribal region, officials say.
Four missiles hit a compound in South Waziristan district on the Afghan border on Wednesday morning.
Intelligence officials said most of the victims were local Pakistani Taliban fighters.
Drone attacks have focused on North and South Waziristan, where US officials believe many al-Qaeda and Taliban fighters find shelter.
The US says the region is home to several militant groups involved in attacks on Nato forces in Afghanistan.
The frequency of the attacks has increased since President Barack Obama took office in 2008. More than 100 raids were reported in the area in 2010, and more than 60 have taken place this year.
The US does not routinely confirm drone operations, but analysts say only American forces have the capacity to deploy such aircraft in the region.
