The Kremlin said Sunday that Russian President Vladimir Putin has been warned of a possible plot to kill him during a visit to Iran this week.

Interfax news agency first reported the assassination plot, citing Russian special services, who were told a gang of suicide bombers would try to kill Putin in Tehran.

After arriving in Germany on Sunday evening for a Monday meeting with Chancellor Angela Merkel, Putin waved a hand dismissively when asked about the matter and told reporters, "later."

Iran said the allegation was baseless, describing it as "psychological warfare" by Tehran's enemies. The Kremlin told Reuters that there were no plans to cancel Putin's visit with President Mahmoud Ahmadinejad on Tuesday.

Putin will be the first Kremlin leader to travel to Iran since Josef Stalin attended a 1943 wartime summit with Britain's Winston Churchill and U.S. president Franklin D. Roosevelt.

Officials have reported uncovering at least two other plots to kill Putin on foreign trips since he became president in 2000.
