Moscow attack: detention of three other suspects requested by investigators. The four alleged attackers were already placed in pre-trial detention on Sunday after their appearance in a Moscow court.
Authorities announced Saturday that they had arrested a total of eleven people, and it was not immediately clear whether these three individuals were among them or not. The profile of the suspects remains unclear. The massacre committed Friday at Crocus City Hall, in the suburbs of Moscow, left at least 137 dead. It is the deadliest attack on European soil claimed by the jihadist group Islamic State (IS)
