Ukraine alleges 'Russian trace' in Poland blast

Kyiv is "completely open to a comprehensive study of the situation," he wrote on the council's official Facebook page. Danilov echoed Ukrainian President Volodymyr Zelenskiy in blaming Russia's "missile terror".

Ukraine has evidence of a "Russian trace" in an explosion in eastern Poland which Warsaw and NATO say was probably caused by a Ukrainian air defence missile, a senior Ukrainian defence official said on Wednesday, without giving any details.

Oleksiy Danilov, Secretary of the National Security and Defence Council of Ukraine, said Ukraine wanted a joint study of Tuesday's incident with its partners and to see the information that provided the basis for its allies' conclusions. Kyiv is "completely open to a comprehensive study of the situation," he wrote on the council's official Facebook page.

Danilov echoed Ukrainian President Volodymyr Zelenskiy in blaming Russia's "missile terror". Danilov provided no details of what evidence he was citing when he referred to a "Russian trace" behind the incident. Polish President Andrzei Duda said earlier it was "highly probable" that the missile was fired by Ukrainian air defence.

Asked whether Poland would grant Ukraine access to the site of the explosion and agree on a joint study, Polish Foreign Ministry spokesman Lukasz Jasina wrote by email: "We do not comment on this matter." Earlier on Wednesday, NATO Secretary-General Jens Stoltenberg said the blast, which killed two people, was probably caused by a Ukrainian air defence missile but that Russia was ultimately responsible because it started the war in Ukraine.
