Russia arrests suspects following Moscow concert massacre with 93 fatalities

In a tragic incident, at least 93 people have been confirmed dead, including three children, following an attack at the Crocus City Hall concert venue on the outskirts of Moscow. The casualties occurred as a result of gunshot wounds and toxic smoke inhalation. In response to the event, Russian authorities have detained 11 individuals. Four of the detained are believed to be directly involved in the attack, as reported by the head of Russia's Federal Security Service to President Vladimir Putin.

The Islamic State group has claimed responsibility for the attack through social media statements, marking this as the deadliest act of terrorism on Russian soil since the Beslan school siege in 2004. However, official sources including the Kremlin and Russian security services have not yet confirmed the attribution of the attack.

The international community, including the U.N. Security Council, has condemned the incident, describing it as a "heinous and cowardly terrorist attack" and has called for accountability for the perpetrators. Meanwhile, U.S. intelligence agencies, as per a source close to the Islamic State, have confirmed the group's involvement in the attack. This violent act comes amidst escalating tensions in Russia's ongoing conflict in Ukraine.
