WATCH: 19 Dead After Blast at Ariana Grande Manchester’s Concert

Nineteen (19) people are reportedly dead and dozens are wounded after an explosion at Ariana Grande concert in Manchester, England on Monday night, May 22, 2017.

Police have not confirmed the cause of the explosion, which happened around 10:30 p.m., but it is being treated as a terrorist incident.

Authorities confirmed, it would be the deadliest attack on Britain after London’s transport system bombings in July 2005.

Here is the full statement from Greater Manchester chief constable Ian Hopkins:

“I can confirm the details of events tonight that we currently know. At around 10.33pm last night we received reports of an explosion at the Manchester Arena in the city centre. It was at the conclusion of an Ariana Grande concert.”

Currently we have 19 people confirmed to have died and around 50 people injured.

The injured are being treated at six hospitals across Greater Manchester. My thoughts are with all those who have been affected and we are doing all we can to support them.

Officers from GMP and emergency services are working at the scene and are supporting those affected. We are coordinating the response from GMP headquarters.

An emergency number is available for those who are concerned about loved ones or anyone who may have been in the area. It is 0161 856 9400.

We are currently treating this as a terrorist incident until we know otherwise. We are working closely with the national counter-terrorism policing network and UK intelligence partners.

This is clearly a concerning time for people but we are doing all we can, working with local and national agencies to support those affected and gather information about what has happened tonight. As you will understand, we are still receiving information and updates, so will provide more details when we have a clearer picture.

I want to thank people for their support and would ask them to remain vigilant and if they have any concerns report them in confidence to us on the anti-terrorist hotline: 0800 789321.

It is important people avoid the area so that we can effectively deal with the incident.”

Meanwhile, Grande, who was not hurt in the blast, has now tweeted that she is “broken” by news of the casualties:
