Ukrainian activists are currently blocking trucks from crossing the border from Poland to Belarus.
The activists demanded that the European Union stop its trade with Russia.
"Every product and every euro that feeds the Russian economy kills Ukrainians," they said on a Facebook page devoted to the protest.
One of the Ukrainian activists, Iryna Zemlyana, told the Kyiv Independent there were about 200 protesters on the border. She said the line of trucks currently stretches for more than 30 kilometers.
Zemlyana also said the protest would last until the EU's trade with Russia and Belarus is halted.
Polish Prime Minister Mateusz Morawiecki on March 19 effectively backed the demonstrators and proposed an EU embargo on trade with Russia.
This is the second time the activists are blocking the border for Russian and Belarusian trucks. During the previous rally last weekend, on March 12-14, dozens of protesters blocked the border but were eventually pushed away by the police.
