Russia has demanded Ukraine to arrest and hand over several people including chief of the country's security service (SBU) Vasily Malyuk, over claims they are connected with "terrorist" acts.

"The March 22 bloody terror attack on Moscow's Crocus City Hall, which shocked the entire world, is not the first terrorist attack on our country in recent time. The investigation conducted by Russian competent agencies reveals the Ukrainian trail in these crimes," the Russian Foreign Ministry said on Sunday in a statement.

"Russia has turned over to Ukrainian authorities its demands... for the immediate arrest and extradition of all those connected to the terrorist acts in question," the statement said.

The SBU immediately dismissed the Russian demand as "pointless." Kyiv has previously denied any involvement in the Crocus City Hall attack.

Among the people listed in the statement was the SBU head Malyuk, who on March 25 acknowledged that Ukraine had organized the attack on the Crimean Bridge in October 2022.

The Russian side also demanded that Kyiv immediately stop any support for terrorist activities, and compensate the victims for the damage done.
