Moscow terrorist attack: Russia strengthens claims of Ukrainian involvement. 139 people have been confirmed dead in the terrorist attack that occurred at a concert hall on the outskirts of Russia's capital, Moscow.

Russian President Vladimir Putin has expressed the view that it was carried out by Islamic extremists, while also asserting that Ukrainian involvement is suspected. Meanwhile, Ukrainian President Volodymyr Zelenskiy completely denies his involvement and strongly opposes Russia's claims. It is possible that the Putin administration is further strengthening these claims in order to justify its invasion of Ukraine.
