"Mass Shooting at Moscow Concert Hall Leaves Dozens Dead and Injured, Russian Officials Investigate"

At least 40 people were killed and over 100 wounded in a shooting at a concert venue on the outskirts of Moscow, making it the deadliest attack in the capital region in years. Gunmen in camouflage opened fire, causing a fire and explosion in the building. The Russian government is investigating the incident as a terrorist act, with no clear information on the perpetrators. President Putin has yet to make a public statement, and there are concerns that he may falsely blame Ukraine for the attack. International leaders have condemned the violence, and the U.S. Embassy had issued a warning about possible attacks on large gatherings in Moscow prior to the incident.
