In 2010, the Moscow subway was attacked and dozens were killed in an attack by Chechen separatists. Below is a tweet from Telegram which shows Islamic State affiliated accounts discussing the attack.  The two groups most likely responsible for the attack are pro-Chechen separatists or Islamic State. However, no one has not claimed responsibility yet.
