The Russian air force said more than 100 aircraft, including fighter
jets and bombers, were taking part in the manoeuvres this week in the
central and western military districts.
The move could alarm Western powers which have accused Russia of
beefing up its troops along its border with Ukraine and arming the
rebels in eastern Ukraine, although Moscow denies the accusations.
The manoeuvres include missile-firing practice and will assist
"coordination between aviation and anti-missile defence", Interfax news
agency quoted an airforce spokesman as saying.
He said Russia's latest bomber, the Su-24, was taking part, as well as Su-27 and MiG-31 fighter jets.
