PAKISTAN-AFGANISTAN-US-NATO-UNREST

An Afghan street vendor crosses the border between Pakistan and Afghanistan through Torkham Gate at Torkham on May 20, 2012. There was no sign of Pakistan opening its border crossing to NATO trucks carrying essential supplies to Afghanistan, as President Asif Ali Zardari prepared to meet Western leaders. A furious Pakistan slammed shut the Torkham border gate in its northwest to NATO vehicles in November when air strikes killed 24 Pakistani soldiers, souring already fragile relations between allies Washington and Islamabad.
