Sources are suggesting that tonight's attack in Manchester is that of a terrorist nature. National counter-terrorism officers, according to the BBC, were assembling in London.
An explosion was captured on dashcam footage near the Manchester Arena in an attack that has caused fatalities - as confirmed by Greater Manchester Police.
The explosion happened just after 22:30 BST at the end of an Ariana Grande concert.
The footage, as recorded from a car, show a quick flash of yellow light in the left of the screen where the Manchester Arena is.
Further footage from inside, and around the arena, also showed the distress of the situation.
The Police tweet said: "Emergency services are currently responding to reports of an explosion at Manchester Arena.
"There are a number of confirmed fatalities and others injured. Please AVOID the area as first responders work tirelessly at the scene.
"Details of a casuality bureau will follow as soon as possible."
The Holiday Inn near the arena reported that it was looking after 50 children without a guardian following the incident.
One eye-witness, Jenna-Lea May Alston, told LADbible: "I was sat in block 206 and after the concert had finished my boyfriend, Adam, wanted to leave. I told him to stay and wait until people had gone.
"The lights came on and we heard a massive bang. I've never heard anything like it in my life. It was louder than fireworks. There was screaming, you didn't know what to do.
"We tried to go out, and when we did, two girls opened the doors and instantly ran back screaming that there was a bomb. We all thought the absolute worst.
"Eventually when they told us to evacuate we went down the same set of stairs and all I could see were bodies, smoke and blood. I could see man with blood down his back, and young girls.
"It was by where the old McDonald's used to be. There were bodies lying on the floor, I saw it with my own eyes."
Manchester residents had also taken to social media in support, offering a place to stay for those who may be stranded by the incident.
