**Two suspected US drone missile strikes have killed at least 12 people in a tribal region of north-west Pakistan, Pakistani security officials say.**The missiles targeted a compound described as a Taliban training centre, about 30km west of Miranshah the main town in North Waziristan.
Officials say the first strike killed seven people. Five died in a second attack as they searched for bodies.
It is the fourth suspected US drone attack in North Waziristan in a week.
North and South Waziristan are a major sanctuary for al-Qaeda and Taliban militants.
Hundreds of people, many of them civilians, have been killed in drone attacks since mid-2008. Top Taliban leader Baitullah Mehsud was among them.
Pakistan has publicly criticised drone attacks, saying they fuel support for the militants.
The US military does not routinely confirm drone attacks, but analysts say the US armed forces and CIA in Afghanistan are the only forces capable of deploying drones in the region.
