MOSCOW – Russian President Vladimir Putin has been told about a plot to assassinate him during a visit to Iran this week, a Kremlin spokeswoman said Sunday.
The spokeswoman, who spoke on customary condition of anonymity, refused further comment.
Interfax news agency, citing a source in Russia's special services, said suicide terrorists had been trained to carry out the assassination.
Putin is to travel to Tehran on Monday night from Germany after meetings with Chancellor Angela Merkel.
During his visit to Iran, Putin is to meet with President Mahmoud Ahmadinejad and attend Tuesday's summit of Caspian Sea nations.
He will be the first Kremlin leader to travel to Iran since Josef Stalin attended a 1943 wartime summit with Britain's Winston Churchill and President Franklin Roosevelt.
Officials have reported uncovering at least two other plots to kill Putin on foreign trips since he became president in 2000.
Ukrainian security officials said they foiled an attempt to kill Putin during a summit in Yalta in August 2000. And in 2001, Russian security officials said a plot to assassinate Putin earlier that year in Baku, the capital of Azerbaijan, had been uncovered by the Azeri special services.
Russian officials linked both alleged plots to Chechen separatists. Putin had sent troops back into the southern Russian republic to crush resistance to Moscow's rule.
