Moscow's leading theaters have decided to cancel all performances this weekend. At least 40 people died as a result of the terrorist attack at Crocus City Hall, the Russian FSB reports.
More than 100 people were injured in the attack, which was carried out by a pro-government group. The attack took place in the Moscow region, which is home to many of the country's major theaters. The Russian government has appealed to the public to come forward with information about the attack. It is not clear whether the appeal will be successful.
