CNN's Reza Sayah reports on U.S.-made NATO supplies bound for Afghanistan that are stuck and unused in Pakistan.

The transit points have been closed for nearly half a year as Pakistan and the U.S. negotiate how to resume relations after a series of incidents, including the secret raid by American forces to kill bin Laden and a border fight with NATO troops that left two dozen Pakistani soldiers killed. It has been a costly problem for the U.S. and NATO which must use other, more circuitous routes to get supplies into the country.

Gen. John Allen, commander of US and NATO troops was in Rawalpindi this past weekend to hold discussions with the Pakistani military on a range of issues, including the border situation. A statement released by the Pakistani government said the talks focused mostly on "Talks focused on operations in border areas and coordination mechanisms to avoid untoward incidents."

A U.S. negotiation team went to Pakistan in late April to start intensive talks about resolving the relationship-crippling issues.
