ANKARA, June 15 (Reuters) - Foreign Minister Hakan Fidan told Iranian counterpart Abbas Araqchi in a call on Monday that Turkey hoped further talks with the U.S. would yield positive outcomes after an Iran-U.S. deal to halt the war, a Turkish diplomatic source said.

Fidan also warned against "provocations" that could derail the agreement and vowed that Turkey would continue supporting efforts for regional peace, the source said. Araqchi thanked Turkey for its efforts in the negotiation process, the source added.
