Pakistan reopened border crossings into Afghanistan for U.S. and NATO troops this week after a seven-month closure of the supply routes.
The borders are a key supply route for the United States military and the reopening could save the U.S. hundreds of millions of dollars,
Pakistani officials closed the borders in retaliation for NATO air strikes that accidentally killed 24 Pakistani border troops in November of 2011.
During the closure, the U.S was forced to use more costly and lengthy routes through the former Soviet Union. After months of back-and-forth negotiations, Pakistan opened the routes after Secretary of State Hillary Clinton apologized for the border deaths.
A Pakistani official said the first truck carrying supplies to U.S. and NATO troops in neighboring Afghanistan crossed the border around noon local time on Thursday.
The move could signal an improved relationship between the U.S. And Pakistan.
