Police in Manchester, England, said at least 22 people, as well as the attacker, were confirmed dead after reports of an explosion at an Ariana Grande concert on Monday night. Police said 59 more people were injured. Among them are 12 people under the age of 16.

Police said they believed the attack was perpetrated by one man who was “carrying an improvised explosive device.”

People were warned to avoid the arena area, and the Victoria transit station was shut down during the police investigation. Many Manchester taxis offered free rides to people stranded in the area.
