WARSAW - A Russian SU-24MR military jet flew into Polish airspace in the Gdansk bay area of the Baltic Sea on Tuesday due to what Russia said was an navigation system failure, the Operational Command of the Polish armed forces said.

Poland's army said a Russian aircraft briefly violated the airspace over the NATO country's territorial waters Tuesday in the latest incident over the strategically located Baltic Sea, AFP reported. Poland -- a staunch ally of war-torn Ukraine -- shares a border with the Russian exclave of Kaliningrad and has called for ramped-up protection of the Baltic Sea from acts of sabotage.
