Poland’s prime minister Mateusz Morawiecki has convened an urgent meeting of a committee for national security and defence affairs, the government spokesman Piotr Müller said on Twitter.
Müller did not mention what the committee was due to discuss but local media reported that the meeting may be related to a reported explosion on the Polish border with Ukraine.
Russia shelled cities and energy facilities across Ukraine on Tuesday, including Lviv, a city in the west of the country close to Poland.
