(AFP) — Russian President Vladimir Putin on Saturday vowed to punish those behind a “barbaric terrorist attack” on a Moscow concert hall that killed at least 133, saying Russia had arrested four gunmen who were trying to flee to Ukraine.
Kyiv has strongly denied any connection, and Putin made no reference to claims of responsibility by the Islamic State in his first public remarks on the attack.
At least 133 people were killed when camouflaged gunmen stormed the Crocus City Hall, in Moscow’s northern suburb of Krasnogorsk, and then set fire to the building on Friday evening.
