Ukraine’s President Volodymyr Zelensky says Moscow is deepening military coordination with Tehran as well as North Korea and China, Al Jazeera reports.

In an interview with Sky News, Zelensky has said North Korea could send 30,000 troops to Russia while Iran may provide additional missiles.

Asked whether he’s concerned about a potential Iranian attack on Ukraine, Zelensky says Tehran is already involved in the war by supplying weapons to Russia.

“We can’t trust these people because at the very beginning, without any escalation from our side, Iranians gave weapons,” he has said.

“We have to do everything not to open a new front [but] Iranians and North Koreans already attacked us.”
