KABUL, Afghanistan (AP) — Afghanistan's president is warning that any further delay turning over a key U.S.-run detention facility to full Afghan control would harm relations.

Hamid Karzai's statement comes after he and U.S. commander Gen. Joseph Dunford met Wednesday but failed to resolve the impasse that derailed a scheduled handover last Saturday.

NATO released a statement after the meeting saying both parties pledged to continue constructive dialogue to resolve the remaining issues.

The facility has an Afghan administrator but is still U.S.-run. The Americans also have the power to veto the release of detainees they feel present a continuing threat — a right they want to keep.

Karzai pledges that even after Afghans take over, they will keep anyone who is a security threat in custody.
