Pakistani fighter jets have targeted suspected militant hideouts in the Orakzai tribal agency, south-west of Peshawar, killing at least 10 people. Officials say, the dead were militants, but eyewitnesses say the bombs destroyed the home of a tribal chief, killing three women and four children. Pakistani troops have been engaged in a major offensive against the Taliban in South Waziristan, further south. The army believes many insurgents fled from there to areas such as Orakzai. A number of air strikes have targeted militant targets in Orakzai in recent weeks. The United Nations says, more than 40,000 civilians have left their homes in Orakzai and are in need of humanitarian assistance.
