MOSCOW, June 12 (RIA Novosti) - More than 200,000 law enforcement officers will ensure security of Russian citizens during the celebrations dedicated to Day of Russia, a senior Interior Ministry official said Monday.

Day of Russia is an Independence Day holiday in the Russian Federation celebrated on June 12. On this day, in 1990, the Russian parliament formally declared its sovereignty. The holiday has been officially recognized since 1991 when it was established by Boris Yeltsin, who was the president of the Russian Federation at the time.

Alexander Chekalin, first deputy interior minister, said police patrol and quick-response units had been strengthened all around the country, especially in places of mass gathering of people, including airports, railway stations, and at high security facilities.

The police said traffic in the center of Moscow had been restricted for the duration of the festivities.
