The blast that killed two people in Poland near its eastern border put Ukraine’s air defenses under the spotlight as Kyiv’s allies face growing pressure to deliver more aid to fend off intensifying Russian attacks.
NATO and Poland attributed the incident to Ukrainian forces trying to shoot down the scores of rockets fired on Tuesday in one of Russia’s biggest barrages during the war, which could potentially spur more deliveries of anti-air weapons by western nations.
NATO Secretary-General Jens Stoltenberg and Polish President Andrzej Duda said the incident did not appear to be the result of a deliberate military attack against Poland or NATO. But the alliance said Russia — not Ukraine — was ultimately to blame for waging a war that risks spilling over into allied territory.
