MOSCOW (Reuters) - Russia must boost its combat readiness in response to NATO's "aggressive actions" near Russia's borders, President Vladimir Putin said on Wednesday.

Addressing parliament on the 75th anniversary of Nazi Germany's attack on the Soviet Union, Putin berated the West for being unwilling to build "a modern, non-bloc collective security system" with Russia.
