The tragic event at Moscow's Crocus City Hall on March 22, 2024, where gunmen in combat attire opened fire and set off explosives, resulted in at least 115 fatalities and 187 injuries, including children.
This attack, which ISIS claimed responsibility for, marks one of Russia's most devastating incidents since the 2004 Beslan school siege.
The assailants targeted the audience gathered for a concert by the rock band Picnic, causing a massive fire and chaos as people scrambled for exits.
Despite ISIS's claim, Russia has raised suspicions about the group's involvement, pointing instead towards possible connections to Ukraine.
However, the US has intelligence confirming ISIS's responsibility for the attack.
Four suspects have been detained and appeared in court, showing signs of severe injuries, which authorities claim occurred during their capture.
This incident has prompted heightened security across Moscow and a wave of global condemnation against the act of terrorism.
