Andriy Yusov, a representative of the Defence Intelligence of Ukraine, said this in a comment to media.
"This is a deliberate provocation by Putin's special services, which the international community has warned about. The Kremlin tyrant started his career with this and wants to end it with the same crimes against his own citizens," said Andriy Yusov.
Ukraine is not involved in the terrorist attack in Moscow. Mykhailo Podolyaka, a representative of the Presidential Administration, also said this.
The Freedom of Russia Legion and the Russian Volunteer Corps also said they were not involved.
"We emphasize that the Legion is not at war with peaceful Russian civilians. "Ryazan sugar" (Russian apartment bombings - ed.) is a method of Putin's security forces that we do not support and are fighting against," the Legion emphasized.
