WASHINGTON (AP) — The United States and Cuba will resume talks this week on restarting direct mail service despite a deadlock between Washington and Havana over detainees that has largely stalled most rapprochement efforts, a U.S. official said Monday.

U.S. and Cuban diplomats and postal representatives will meet in Washington on Tuesday and Wednesday for technical talks aimed at ending a 50-year suspension in direct mail between the United States and the communist island. The official spoke on condition of anonymity because he was not authorized to speak to the matter publicly before Congress is notified. Lawmakers were to be notified of the meetings starting Monday morning, the official said.
