The opposition to the appearance of soldiers from North Korea in the Russian Federation should be quite strong; the first battles with North Korean soldiers open a new page of instability in the world, said Ukrainian President Volodymyr Zelenskyy.

"I want to thank everyone in the world who responded to the appearance of North Korean soldiers in Russia. And who responded not only with words, but are also preparing appropriate actions to support our defense here in Ukraine. Terror, unfortunately, can spread like a virus when it does not meet with sufficient resistance. Now the resistance must be sufficient. Strong enough. The first battles with North Korean soldiers open a new page of instability in the world," Zelenskyy said in his video address on Tuesday evening.
