A Russian Su-24 tactical bomber was intercepted by the Polish Air Force over the Baltic Sea last night, Poland's defence minister revealed today.

Wladysław Kosiniak-Kamysz said that a pair of Polish jets were scrambled after the joint operational command for NATO forces in Europe issued the order to intercept.

They located the aircraft in international airspace over the Baltic late on Thursday, before intercepting and 'effectively deterring' it, he said.

'The Russian Federation's Su-24 aircraft was performing dangerous manoueuvres,' Kosiniak-Kamysz told reporters.

He said such manoueuvres 'show what the intentions of this action are, that this is not an accidental action, but an intentional action'.
