Joint Russian-Mongolian antiterrorist drills will begin later on Thursday and last until September 10, a spokesman for the Russian Air Force commander said.
In the scenario of the Selenga 2011 exercises, the Russian and Mongolian military destroy militant gangs that have been trying to seize several important facilities in northern Mongolia, Igor Muginov said.
Some 500 Russian and Mongolian servicemen will take part in the exercises, which will also involve up to 200 military vehicles.
The drills will be held in two stages: the first will take place in the Russian republic of Buryatia in eastern Siberia, and the second in Mongolia.
