Ukraine has uncovered a plot for an attempted coup with the involvement of Russians, due to have taken place next week, President Volodymyr Zelensky said on Friday at a press conference.
Zelensky did not give full details of the coup plot and did not accuse the Russian state of involvement, though he also spoke at length at the press conference of a threat of Russian military escalation, and said Ukraine would be ready for it.
The Kremlin swiftly denied any role in any coup plot, saying it had no plans to take part in such acts.
Russia has been building up forces near its border with Ukraine. Kyiv, the United States and NATO have voiced concerns in recent days about a possible Russian attack -- a suggestion the Kremlin has dismissed as false and alarmist.
"We have challenges not only from the Russian Federation and possible escalation - we have big internal challenges. I received information that a coup d'etat will take place in our country on Dec. 1-2," Zelensky said.
