The PSNI has said it has requested additional officers from across the UK in order to combat rising violence and disorder in Belfast.
Last Saturday saw large anti-immigration protests across Northern Ireland while violence and disorder has escalated across recent days.
Six people have been charged, including three teenage boys while three police officers have been injured.
In a statement, Assistant Chief Constable Melanie Jones said the request for additional officers was in direct response to the ongoing trouble while the PSNI itself would be mobilising its service across the coming days.
“As a result of the ongoing street violence and disorder we have seen across Belfast since the weekend the Police Service of Northern Ireland has taken a decision to significantly mobilise the service. Unfortunately this will mean officers and staff working longer shifts and rest days,” she said.
“Increasing our resources and footprint across Northern Ireland in the coming days will enable us to manage planned events and deal with any sporadic incidents, including disorder.
“We have also submitted a request to National Police Co-ordination Centre for additional officers from across the United Kingdom to support the policing operation.”
The National Police Coordination Centre (NPoCC) provides support to forces across the United Kingdom, Crown Dependencies and British Overseas Territories.
It co-ordinates the deployment of officers and staff from across UK policing to support forces during large-scale events.
ACC Jones added: “The Mutual Aid officers will provide vital resilience and support and will be given all of the necessary equipment and familiarisation training.
“Any officers who may come to Northern Ireland would specifically assist with the ongoing public disorder and protests and not every day policing.
“We will continue to keep this under review.”
