Russian President Vladimir Putin is to visit Iran in August to try and restart talks on Tehran’s nuclear program

Russian President Vladimir Putin is to visit Iran in August to try and restart talks on Tehran's nuclear program, Russia's Kommersant daily reported on Wednesday.

Putin's visit is planned for mid-August, shortly after Iran's new president Hasan Rouhani formally takes office on August 3, Kommersant reported, citing sources in the Kremlin and the Iranian foreign ministry.

Putin's spokesman Dmitry Peskov told AFP: "I cannot so far confirm this".

Moscow hopes the visit will provide impetus to restart the currently stalled talks on Iran's nuclear program, the newspaper cited sources as saying.

Kommersant cited a source in the Iranian foreign ministry as saying the trip would take place August 12-13. It said a Kremlin source confirmed the trip, but said it was not yet decided whether it would last one or two days.
