"Russian Concert Attack: US Warned of Planned Terror Attack a Month Ago"

The United States had warned Russian authorities about a potential terrorist attack targeting large gatherings in Moscow earlier in March, according to the White House. This warning came to light after a mass shooting outside the Russian capital left at least 60 people dead. The US government shared this information with Russian authorities as part of its "duty to warn" policy. The attack, which occurred at a Moscow concert hall, resulted in over 60 deaths and more than 100 injuries, with the Islamic State group claiming responsibility.
