Russian President Vladimir Putin is scheduled to pay a visit to Tehran on Tonight to attend a summit of the Caspian Sea littoral states.

Head of the Muslim Scholars’ International Union Sheikh Yusef Gharzawi said that defending Iran against enemies is a religious duty for all world Muslims.

Russian President Vladimir Putin will visit Iran this week despite a warning by his secret service that an alleged plot to assassinate him has been in the works, the Kremlin press service said Monday.
