Russia’s Federal Security Service said the gunmen had contacts in Ukraine and were captured near the border.
The claim was dismissed by Ukrainian President Volodymyr Zelensky. Ukrainian Foreign Minister Dmytro Kuleba said in a statement on the social media platform X on Sunday that “there is no evidence to support such claims”.
The White House said that Washington had shared information with Moscow early this month about a planned attack, and issued a public advisory to United States citizens in Russia on March 7. It said Islamic State bore sole responsibility for the attack.
“Nothing was passed,” Russian Ambassador to the US Anatoly Antonov responded early on Sunday, saying that Washington did not share any specific information with the embassy before the terrorist attack.
