KYIV, Nov 16 (Reuters) - 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.
Kyiv is "completely open to a comprehensive study of the situation", he wrote on the council's official Facebook page.
Danilov provided no details of what evidence he was citing when he referred to a "Russian trace" behind the incident.
Duda said earlier it was "highly probable" that the missile was fired by Ukrainian air defence.
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.
