Russia has announced a set of measures to ensure security at next month's Winter Olympics in Sochi.

According to official reports, 37,000 police officers from around the country will patrol Sochi.

An additional 23,000 members of the Ministry for Civil Protection are to be stationed in the city, as well as numerous soldiers, border patrol and an unknown number of intelligence agents, Deutsche Welle says.

Naval vessels and submarines will patrol the coast while drones and fighter jets guard the Games from the skies. Dozens of extra police cruisers already patrol the Sochi area. Police from other Russian cities have been in Sochi for weeks, testing routes and practicing response tactics. About 1,400 video cameras have been installed throughout the city and quad vehicles stand ready for use in the mountains.

Russian President Vladimir Putin has increased security in the country following two suicide bomb attacks in the southern city of Volgograd which killed at least 34 people.
