The Russian government has accused Ukraine of financially backing the attack at a Moscow concert hall killing over 140 persons with several out injured.
An investigative committee made this disclosure on Thursday in Moscow.
President Putin said that a group of terrorists looking like a radical Islamist, stormed a large music venue just outside of Moscow to wreck havoc.
They went on a gun rampage, killing people on sight as they went towards the main hall, and set it on fire.
Russian officials had claimed that the terrorist attack at the Crocus City Hall may have been organised by Ukrainian special services who used the Islamists as proxies.
The committee said: “Confirmed information [indicated] that perpetrators of the terrorist act had received significant sums of money and cryptocurrency from Ukraine, which were used in the preparation of the crime.”
According to him, people seriously hurt in the terrorist attack eventually died from their injuries.
