"Russia Arrests Suspects in Moscow Concert Hall Shooting; ISIS Claims Responsibility for Deadly Attack"

Russia detains 11 suspects after at least 93 people were killed in a concert hall shooting in Moscow, with ISIS claiming responsibility for the attack. The gunmen were stopped in the Bryansk region, and four of those detained were directly involved in the attack. The Islamic State group claimed responsibility for the attack, although the Kremlin and Russian security services have not officially assigned blame. The attack came just days after President Vladimir Putin solidified his power, and it was the deadliest in Russia in years. Videos showed gunmen shooting civilians at point-blank range, and the roof of the theatre collapsed during the firefighting efforts. Messages of outrage and support have poured in from around the world, and hundreds of people in Moscow lined up to donate blood and plasma.
