An Air Force fighter jet has been shot down by an air-to-air missile fired from a Russian plane, a spokesman for Ukraine's Security Council said Thursday. Andrei Lysenko also said Ukrainian troops had been fired upon by missiles from a village just inside Russia. Officials in Kyiv have recently accused Russia's armed forces of being directly implicated in attacks on Ukrainian troops battling an insurgency near the border. Lysenko said in a televised briefing that the pilot of the Sukhoi-25 jet that was hit on Wednesday evening was forced to bail out after his jet was shot down. He provided no further details.
