Birmingham Police Commander Richard Moore, said: "At this stage there are no West Midlands Police officers inside the prison. This operation will be led by the Prison Service and its specialist teams which are well-drilled in tackling such situations.

There have been a string of warnings about safety behind bars after statistics revealed soaring levels of violence in jails in England and Wales, with assaults on staff up by 43% in the year to June.

"Currently the whole facts surrounding the incident at HMP Birmingham are not known,'' he added.
"National resources have been deployed to deal with this incident involving approximately 300 prisoners within two prison wings.
"No staff injuries have been reported and staff are currently monitoring the situation and awaiting national support, through mutual aid.''
13.15 A spokesman for the West Midlands Ambulance Service confirmed they were called to the prison at 12.23pm.

The Victorian category B jail, which was built in 1849 and is close to the city centre in Winson Green, can hold 1,450 adult remand and sentenced male prisoners.
A G4S spokesman said: "We are responding to an ongoing incident at HMP Birmingham this morning which began just after 9am involving two wings of the prison.
"We are working with colleagues across the service to bring the incident to a safe conclusion.''
Prison affairs academic and blogger Alex Cavendish told the Press Association an "inside informant'' told him the trouble started with lights being broken and inmates controlling fire hoses.
"The officers were then, as they are instructed to do, trying to get as many prisoners locked in their cells as possible to contain it,'' he said.
"While one of the officers was putting a prisoner in the cell he was threatened with what appeared to be a used syringe."
Mr Cavendish said while this officer was distracted by the threat, "another inmate came up behind, snatched the keys from his belt and snapped the security chain''.
He told the Press Association that once prisoners have control of the keys, protocol tells the officers to ``withdraw to a place of safety'' and said they "abandoned the wing'' where the incident started.
The 53-year-old said inmates have since gained access to the offender management unit (OMU), where their paper records are stored and which are now being burnt.
"I am hearing there is a very badly injured casualty (prisoner), and the prisoners are throwing computers out of the OMU window - destroying records,'' Mr Cavendish added.
Describing the incident as "probably most serious riot in a B category prison since Strangeways went up'' in 1990, he said: "It is a very serious situation and I think the fact they have now accessed the key offices like the offender management unit - that is where all the offender records are.
"If they destroy all of those records it is going to take months or even years to rebuild the information.''
11.57 A G4S spokeswoman said: "We are responding to an ongoing incident at HMP Birmingham this morning which began just after 9am involving two wings of the prison.
"We are in close contact with the National Offender Management Service (NOMS) , and are working with colleagues across the service to bring the incident to a safe conclusion.''
