Negotiations between the United States and Pakistan on reopening ground supply routes into Afghanistan have stalled.
A Pentagon spokesman, George Little, said on June 11 that Washington has called its negotiating team home.
He said part of the U.S. team left Islamabad over the weekend and the rest will leave shortly.
Little says they are prepared to return on short notice if circumstances change.
He added that a senior Pentagon official, Peter Lavoy, talked to high-ranking Pakistani officials over the weekend but was not allowed to meet with General Ashfaq Parvez Kayani, chief of the Pakistani army.
The supply routes were closed last November by Pakistan in retaliation for a U.S. air assault that killed 24 Pakistani soldiers.
The border crossings had been an important route for getting U.S. war materiel into Afghanistan.
