A&E departments across Wales under 'extreme pressure'
A&E departments across Wales are facing "unprecedented demands", prompting health boards to urge the public to attend only if necessary.
At least five hospitals have declared the highest alert, level four, meaning they are under "extreme pressure".
It comes as some hospitals in England declared a "black alert", saying they are "overwhelmed" by demand.
The Welsh government said winter plans were working and the situation was "broadly beginning to stabilise".
A spokesman added: "The last few days have seen further, more severe surges in demand following the festive period, especially for emergency ambulance calls, GP out of hours consultations and attendances at emergency departments - all of which have seen a greater proportion of elderly and frail patients with complex needs."
NHS Wales has four main status levels used to determine appropriate responses, level one indicating a "steady state" and level four meaning the service is under "extreme pressure".
Level four alerts have been issued for Ysbyty Maelor in Wrexham, Ysbyty Glan in Clwyd, Prince Charles in Merthyr and Royal Gwent in Newport.
A level three alert is in place for Ysbyty Gwynedd in Bangor, with level two alerts for the remaining hospitals.
