Thousands of people have rallied in northwestern Pakistan to protest ongoing U.S. drone attacks that killed scores of civilians. On Sunday, demonstrators in the city of Peshawar blocked a main road and held a vigil to mourn drone attack victims. According to Agence France-Presse, U.S. drone attacks doubled in the North Waziristan region last year, with over 100 drone strikes killing more than 670 people. At least 13 people were killed in three recent attacks.
