ISLAMABAD, Pakistan — Pakistan and the United States signed a deal regulating the shipment of American troop supplies to and from Afghanistan on Tuesday, prompting Washington to agree to release more than $1 billion in frozen military aid.
The developments represent the formal end to a crisis between the two countries that started in November when Pakistan closed its border to supplies meant for U.S. and other NATO troops in Afghanistan in retaliation for American airstrikes that killed 24 Pakistani soldiers.
Pakistan reopened the route running overland through its territory from the southern port of Karachi to the Afghan border in early July after the U.S. apologized for the deaths, which the Americans said were an accident. But it took several more weeks for the two sides to finalize the new agreement.
