A US drone has fired missiles into Pakistan's troubled tribal Waziristan region, killing at least eight people and injuring several others. The missile strike took place in the same region where five people were killed on Monday. Local TV channels reported Tuesday the unmanned aircraft fired two missiles to hit a compound, some five kilometers northwest of Miranshah, the main town of North Waziristan. A local intelligence source confirmed the causalities. The death toll is expected to rise as some of the wounded are said to be in serious condition.
