“In fact, it is an attempt to create North and South Korea in Ukraine,” Kyrylo Budanov, the head of Ukrainian military intelligence, said in a statement, referring to the division of Korea after World War Two.

He predicted Ukraine’s army would push back Russian forces.

“In addition, the season of a total Ukrainian guerrilla safari will soon begin. Then there will be one relevant scenario left for the Russians, how to survive,” he said.

Ukraine’s foreign ministry spokesperson also dismissed talk of any referendum in eastern Ukraine.

“All fake referendums in the temporarily occupied territories are null and void and will have no legal validity,”Oleg Nikolenko told Reuters.
