In one of the worst terror attacks on Russia in years, 40 people lost their lives and more than 100 were injured as gunmen opened fire at Crocus City Hall in Moscow's outskirts during a rock concert.

Moscow's Mayor, Sergei Sobyanin said his government would cancel all cultural, sporting, and mass events for the weekend.

On March 7th, the U.S. Embassy warned people that extremists were targeting large gatherings, like concerts, in Moscow. On that same day, Russia reported that they took out an ISIS cell plotting to attack synagogues.
