WARSAW: Two people died in an explosion in Przewodow, a village in eastern Poland near the border with Ukraine, firefighters said on Tuesday.

"Firefighters are on the spot, it's not clear what has happened," said Lukasz Kucy, officer on duty at a nearby firefighters' post.

Polish Radio ZET reported earlier that two stray missiles hit Przewodow on Tuesday, killing two people, without giving any more details.

Russia was pounding cities across Ukraine with missiles on Tuesday, in attacks that Kyiv said were the heaviest wave of missile strikes in nearly nine months of war.

Polish Prime Minister Mateusz Morawiecki has called an urgent meeting of a government committee for national security and defense affairs, the government spokesman said on Twitter.

A government security spokesman and a representative of the prime minister's office declined to comment further.

State-run news agency PAP reported that the Polish government would hold a meeting at 2000 GMT.

Muller told reporters later on Tuesday that the committee was convened due to the "crisis situation", adding that relevant information will be presented to the public later. He called on media not to publish "unverified information" in the meantime.
