Putin: Russia will respond to NATO 'muscle-flexing' near borders

Russia will react to NATO "muscle-flexing" near its frontiers, the ITAR-Tass news agency quoted President Vladimir Putin as saying Tuesday. "In violation of previous agreements, military resources of NATO members are being built up next to our borders. Of course, we cannot allow ourselves to remain indifferent to this obvious muscle-flexing," ITAR-Tass quoted Putin as saying at a meeting of top military officials. Putin also reportedly said that Russia would increase the combat-readiness of its strategic nuclear forces to ensure a "swift and adequate response to any aggressor."
