NATO Secretary General Jens Stoltenberg and Ukrainian President Volodymyr Zelensky had a telephone conversation.

APA reports that Stoltenberg said this on Twitter.

"I spoke with President Zelenskiy and said that our NATO allies' support for Ukraine's sovereignty and right to self-defense is unwavering.

The fake referendum held by Russia has no legitimacy and is a clear violation of international law.

These lands are Ukraine," NATO Secretary General said.
