"Ending the war in Yemen will pave the ground for de-escalation in the region ... we want peace and calm in the region ... regional crisis can be resolved through diplomacy and co-operation between the regional countries," Rouhani told a news conference, broadcast live on state TV.
He added that relations between Iran and the United Arab Emirates, part of the Saudi-led coalition fighting in Yemen, had improved in the past months and "officials have visited each others countries."
