A Ukrainian man who lives in Poland said he will go back to fight for his country if the situation deteriorates.
"I will go and fight, and I am ready to die for my land. ... I will fight for democratic and freedom country for the law, and it's my duty," he told CNN's Scott McLean at a train station in Przemyśl, where Ukrainian refugees have been crossing into Poland.
Ukraine has banned all male citizens ages 18 to 60 from leaving the country, according to the State Border Guard Service.
Trains from Kyiv are delayed because there are delays with the IT systems, according to Polish authorities, McLean reported.
Cases of water and food are at the train station in anticipation of the refugees.
