Iranian foreign minister's visit to Turkey postponed; no explanation provided

Turkish officials say Iranian Foreign Minister Jawad Zarif has postponed his visit to Turkey.

Zarif was scheduled to hold talks with his Turkish counterpart, Mevlut Cavusoglu, on Tuesday. It would have been his first visit to Turkey since last month's landmark deal on Iran's nuclear program.

Turkey's Foreign Ministry said the visit has been postponed until an unspecified date in the future, but did not provide a reason for the delay.

Turkish media reports said Zarif planned to brief Turkish leaders on an Iranian plan to end the Syrian civil war.
