ISLAMABAD: A high-level US Senate delegation met Pakistan’s top foreign affairs official and powerful military chief in Islamabad to discuss regional security as Washington gears up to send more troops to neighboring Afghanistan. The Sunday visit by members of the influential Senate Armed Services Committee, including top Republican John McCain, came days after Islamabad slammed Washington’s decision to sanction a Kashmiri militant leader. McCain described US engagement with Pakistan in the region as “important” in his meeting with Foreign Affairs Adviser Sartaj Aziz, according to a foreign ministry statement. Aziz for his part vowed Pakistan remained committed to “constructive engagement” with the US in the efforts to create a “stable and prosperous” Afghanistan. He said Islamabad was ready to deepen its partnership with Washington in the fight against militancy, including against the expanding footprint of the Islamic State group in the region.
