A mass riot involving about 180 prisoners has broken out in a jail housing mainly sex offenders in England.
The British Ministry of Justice says national resources have been deployed to deal with the riot at Maidstone Prison.
A spokeswoman for the Ministry of Justice said: "I can confirm there is an ongoing incident involving a number of prisoners and national resources have been deployed. It is confined to one wing."
Prison Officers Association vice chair Ralph Valerio said he was hearing from officers at the scene that up to 180 prisoners are involved.
Valerio said officers on site had the training and skills necessary to bring the mass riot under control.
