Moscow - A Russian Navy battalion left for Venezuela on Monday, a navy spokesman said, in a show of force in US-patrolled waters that could exacerbate a tense security standoff with Washington.
Last week, two nuclear-capable Russian bombers flew military exercises over the US fleet in the Caribbean at the invitation of US foe Venezuelan President Hugo Chavez, who plans to visit Moscow next week.
There has been no such deployment - including nuclear-powered cruiser Peter the Great which is outfitted with torpedoes, 500 missiles and anti-submarine aircraft - in Western waters since Cold War days.
Joint Russo-Venezuelan naval exercises are set for mid November.
