Ambulance staff have threatened to stop attending emergency calls in flashpoint areas of north Belfast after another paramedic was attacked.
Violence broke out for a second night running when a drunken youth lying with a head injury in the Ardoyne area got up and punched a crew member trying to help him.
On Sunday, a paramedic suffered eye injuries when thugs smashed the window of the ambulance he was in during rioting in the Longlands area of the city.
Union representative Mr Paddy McGlinchy has now warned that crews were no longer prepared to tolerate the attacks. He said: "We are rapidly getting to the stage we just won't be going into these areas.
"If they want to bring the people out to us yes, but unless they start treating us and our colleagues in the fire service with some respect we'll not be going in because they won't allow us to do our job".
