NATO believes Poland blast an 'accident,' Kyiv assails Russia

NATO Secretary General Jens Stoltenberg said an ongoing investigation was expected to find that a missile blast in Poland was likely caused by a Ukrainian air defence missile

Poland put its military on high alert after what the country's president said was 'most probably' a strike by a Russian-made missile

Western leaders moved to calm fears of a dangerous escalation in Russia's war in Ukraine Wednesday, saying a missile blast in Poland was likely an accident, while Kyiv pushed back hard at the idea its anti-aircraft fire was to blame.

In the immediate aftermath the incident sparked fears of a major new escalation in the Ukraine conflict, but by Wednesday President Andrzej Duda announced Poland's conclusion the projectile likely originated from Ukraine's own air defences.
