Pakistan on Saturday defended its military policy in the northwest part of the country amid tensions in its relationship with the United States. In a statement issued by the foreign ministry, Islamabad declared that there was no lack of Pakistani resolve to fight terrorism. The comments come as a wave of US drone strikes in the area continues, having killed more than 150 people and raising tensions between Washington and Islamabad, which condemns the operations as a violation of its sovereignty. A leaked White House report to Congress earlier this month also accused Pakistani forces of avoiding direct conflict in North Waziristan, while ground operations in South Waziristan were only progressing slowly. Militants fighting against more than 150,000 US and NATO troops of the International Security Assistance Force (ISAF) in Afghanistan are believed to be holed up in the tribal region, as are operatives at war with Pakistani security forces.
