VLADIVOSTOK, April 26. /TASS/. Terrorist acts and particularly the hostage crises in the Dubrovka theatrical center in Moscow in October 2002 where a group of radical fundamentalists seized more than a thousand spectators right in the middle of performance of the ‘Nord Ost’ musical, and the September 2004 seizure of a general school in the North Caucasus town of Beslan were the most tragic events over the past fifteen years of Vladimir Putin’s stay in power.

Putin said it in a documentary film ‘The President’ aired by Rossiya One channel on the occasion of the 15th anniversary since his accession to the upper echelons of state power.

"No doubt, these are the terrorist acts - Beslan and Nord Ost," he said. "If you’re asking about the tragic (events), these are the harshest things our entire people had to go through."

Nikolai Patrushev who stood at the head of the Federal Security Service FSB at the time recalled that he made daily reports to the President then.

"I kept Putin updated practically in the real-time mode, day and night, and he didn’t leave his office in those days," he said.
