At least 9 people were killed in two US drone strikes in the Datta Khel area of North Waziristan on Friday evening.
A day earlier, four people were killed when a drone fired two missiles at a house in the Mir Ali area of North Waziristan.
Drone attacks reached unprecedented levels this month. Since US President Barack Obama came into office, there have been more than 143 drone attacks, with about 58 strikes in 2009 (after January 20) and around 85 in 2010.
Drone attacks have stoked anti-American sentiment in the country with many saying they violate Pakistan’s sovereignty.
