ISLAMABAD: US Senator John McCain expressed support for Pakistan’s efforts in the fight against the Taliban after visiting a key tribal district recently retaken by the military, the Pakistani foreign ministry said on Sunday. A four-member, bipartisan US Senate delegation led by the former presidential candidate went to North Waziristan, where in 2014, under US pressure, the army launched an operation to wipe out militant bases and end the near decade-long Islamist insurgency. In May, the army announced it had successfully cleared the area of militants. The foreign ministry statement said that the US delegation had met with Pakistani Foreign Affairs advisor Sartaj Aziz and held talks on Pakistan-US ties as well as the situation in Afghanistan. Aziz “appreciated Senator McCain for his positive comments regarding the importance of Pakistan-US relations at a time when the region was facing complex challenges,” the statement said.
