Ten people, including two children, are in hospital after a shooting in the Moss Side area of Manchester.
Armed officers from Greater Manchester Police were called to Claremont Road, near Rosebery Street, at 2.30am (local time) on Sunday and discovered several people had been hurt.
The injuries range from minor to major, but most do not appear to be life-threatening, police said.
Footage reportedly showing the aftermath of the incident was posted on social media.
The video appears to show a panicked group of people being helped by police.
As a voice cries out, shouts of “Move” can be heard, while another voice asks “Can you hear me?”
A number of people were in the area following the Caribbean Carnival, which had finished some hours before.
Detective Superintendent Debbie Dooley said: “We currently have a number of people in hospital all being treated for different injuries but thankfully most do not appear to be life-threatening at this time.
“Officers are trying to establish exactly where this incident took place and who is responsible for such a dangerous attack.
“The area is being searched and examined while we are also trying to speak to as many people as possible and are reviewing CCTV to get all the facts.”
Police have deployed a “large number” of armed and unarmed officers in the area after the alarm was raised.
Investigations are continuing.
