Jens Stoltenberg, Nato’s secretary general, said on Wednesday that Tuesday's missile blast in eastern Poland appears to have been caused by a Ukrainian air defence missile.
Polish President Andrzej Duda has appealed for people on the eastern border to remain calm as military activity is increased owing to Tuesday's missile blast.
There is little evidence suggesting the need to activate Nato's Article 4 in response to Tuesday's missile blast in eastern Poland, the Polish prime minister said on Wednesday.
Andrzej Duda, Poland’s president, has said there is a “high probability” that the missile that killed two people in eastern Poland on Tuesday was fired by Ukraine’s air defences.
The Ukrainian Air Force said it would support the investigation into Tuesday's missile explosion in Poland "as much as possible".
The president of the European Commission (EC) has offered Poland the organisation’s full support following an explosion near the Ukrainian border that killed two Poles on Tuesday.
The missile landed near the village of Przewodow, which lies about 10 kilometres from the Ukrainian border, on Tuesday afternoon, and came on a day in which Russia launched dozens of strikes on targets across Ukraine.
Volodymyr Zelensky told the G20 summit that Tuesday’s mass missile attacks on Ukraine and the "Russian rockets (that) hit the territory of neighbouring Poland" is "Russia's real appearance at the G20."
The death of two Poles in an apparent strike by a Russian-made missile is the first time since Russia invaded Ukraine that the war has directly affected Poland and claimed lives, a deputy foreign minister said on Wednesday.
The North Atlantic Council, Nato's main decision-making body, will meet on Wednesday at 10 am to discuss Tuesday's missile blast in eastern Poland that claimed the lives of two people, Nato's spokesperson said on Wednesday morning.
