Russian intelligence officers opposed to their country’s invasion of Ukraine reportedly tipped off officials in Kyiv who thwarted an assassination plot against President Volodymyr Zelensky.

The head of Ukraine’s National Security Council Oleksiy Danilov said on social network Telegram that two group of assassins from Chechnya had been involved in the plot.

“We are well aware of the special operation that was to take place directly by the Kadyrovites to eliminate our president,” Danilov said, referring to the fighters from the Caucasus Russian republic whose leader Ramzan Kadyrov pledges unswerving loyalty to President Vladimir Putin.

Danilov said that the Chechens had been divided into two groups, with one under fire in Gostomel, north of the capital Kyiv and the other was “eliminated.”

“The Kadyrov forces unit, which came to kill our President, was eliminated,” Danilov told Ukraine 24 TV. “We will not give our President or our country to anyone. This is our land, get out of here.”

Zelensky has said that he and his family are the Kremlin’s top two targets since Russia’s invasion of Ukraine last week.

While Russia has been reluctant to reveal its casualties during the war, Kadyrov said on Tuesday that Chechens had been killed during the conflict.
