George Murphy from the Welsh Ambulance Services NHS Trust: "The safety and well-being of front-line ambulance staff is of paramount importance to the Welsh Ambulance Services NHS Trust and we will not tolerate any incidents of violence and aggression against staff.
"Unfortunately, incidents of verbal and physical abuse against staff is a continuing problem and as part of the trust's commitment to zero tolerance it has invested in extra training in how to deal with potentially violent and aggressive situations.
"It is appalling that staff have to learn to protect themselves when it is their job to provide emergency care to communities at their time of greatest need."
Gwent Police have arrested two men aged 21 and 19 in connection with the attack and they have been released on police bail. Investigations are on-going.
In 2003/4, there were 179 reported incidents of violence and aggression against staff with 61 resulting in injury.
