Russian President Vladimir Putin's security adviser will meet Thursday with an envoy of Iran's Supreme Leader Ayatollah Ali Khamenei, the security council said Wednesday.
Security Council secretary Igor Ivanov will meet with Ali Akbar Velayati, Ivanov's spokeswoman Kseniya Roshchina said. Both men are former foreign ministers.
Russia has urged Iran to take steps to prove its claims that it is not seeking nuclear weapons, but is a staunch supporter of Tehran's right to a peaceful nuclear energy program.
Ivanov visited Iran late last month and met with Khamenei as well as others including Iran's top nuclear negotiator, Ali Larijani.
