The Pakistani military says it has launched airstrikes in the Datta Khel region of North Waziristan, killing 40 people it identified as suspected militants. The strikes come as part of a major offensive launched in June which coincided with the resumption of U.S. drone strikes in the region. In the Pakistani capital Islamabad, meanwhile, Prime Minister Nawaz Sharif is facing continuing calls for his resignation from protesters led by former cricket star Imran Khan, who has accused Sharif of rigging last year’s elections.
