Poland’s prime minister on Monday called for the establishment of a commission to investigate what he called genocide in Ukraine.

Speaking at a news conference, Mateusz Morawiecki called the Russian attacks in Ukraine "genocide" and recommended the establishment of an international commission to investigate.

Referring to media images of what seem to be mass killings from various regions near the capital Kyiv, including Bucha, he said voices should be raised to take a stand against Russia.

The Russian war against Ukraine, which started on Feb. 24, has been met with international outrage, with the European Union, US, and UK among others implementing tough financial sanctions on Moscow.

At least 1,430 civilians have been killed in Ukraine and 2,097 injured, according to UN estimates, with the true figure feared to be far higher.

More than 4.21 million Ukrainians have also fled to other countries – including some 2.4 million to neighboring Poland – with millions more internally displaced, according to the UN refugee agency./aa
