Two Polish citizens have been killed after a missile landed in eastern Poland

Around 15 miles from the Country’s border with Ukraine

First confirmed instance of the war in Ukraine having caused casualties directly in another Country.

So is Russia attacking Poland now?

The circumstances of the explosion are not clear.

A statement from the Polish foreign ministry initially said the missile was Russian-made.

President Andrzej Duda first told reporters it was “most probably” Russian-made.

He later said there was no concrete evidence of who fired it, and the incident was a one-off.

“We are acting with calm. This is a difficult situation,” Duda told reporters.

Duda said Poland was raising its level of military preparedness.
