The US government and Western allies have said that ISIS is responsible for the attack in Moscow.
“No, there is no, whatsoever, any evidence [of Ukraine involvement],” Harris said. “In fact, what we know to be the case is that ISIS-K is actually by all accounts responsible for what happened.”
According to Putin's statement, the four detained militants were planning to flee to Ukraine. However, Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelenskyy, denied the country's involvement in the attack.
Harris also expressed his condolences to the families of those killed in the attack.
“What has happened in the act of terrorism and the number of people who’ve been killed is obviously a tragedy, and we should all send our condolences to those families,” she said.
On Friday, March 22, unidentified persons in camouflage opened fire during a concert at the Crocus City Hall shopping center near Moscow: more than 130 people were killed and a large number of injured. The FSB says it has allegedly detained the suspects.
Ukraine's Main Intelligence Directorate is convinced that the shooting at the Crocus shopping center in Moscow is a deliberate provocation by the Putin regime, and the Foreign Ministry said the world should strongly reject Russia's false accusations of Ukraine's alleged involvement. The White House also rejected Ukraine's involvement.
On March 23, Putin made an address on the terrorist attack. According to the Russian dictator, Ukraine was "preparing a window" to receive the terrorists who staged the attack in the Moscow region.
A representative of the Ukrainian Defence Intelligence Service, Andriy Yusov, called Putin's statement absolutely false and absurd.
After the attack, the head of the United Russia faction, Vladimir Vasilyev, said that the State Duma would consider and "deeply study" the issue of the return of the death penalty.
On the evening of March 23, Ukrainian President Volodymyr Zelenskyy reacted to the terrorist attack near Moscow for the first time. According to him, Putin and other scum are just trying to shift the blame to someone else.
On Sunday, March 24, the US National Security Council (NSC) rejected Russia's attempts to accuse Ukraine of organizing a terrorist attack on the Crocus City Hall shopping mall near Moscow.
