Russia will eliminate Ukrainian leaders if they are linked to Saturday’s terrorists attack in Moscow.

This was made public by the Deputy Chairman of the Security Council of the Russian Federation, Dmitry Medvedev.

Medvedev said: “If it is proven that Ukraine is behind the attack, the Ukrainian officials of the state will be eliminated as terrorists.

“If it is established that these are terrorists of the Kyiv regime, it is impossible to deal with them and their ideological inspirers differently.

“All of them must be found and mercilessly destroyed as terrorists. Including officials of the state that committed such atrocity. Death for death”, Medvedev, Deputy Chairman of the Security Council of the Russian Federation was quoted to have said.

At least 139 people have been killed after gunmen attacked a packed concert venue on the outskirts of Moscow, Russian intelligence said.

More than 200 were wounded at the Crocus City Hall, the FSB Federal Security Service added.

The Islamic State group has claimed it carried out the attack.
