Caution urged over dialling 999 as A&Es struggle to cope
The Welsh government has urged people to think before dialling 999, as A&E departments across Wales continue to operate under "unprecedented" pressure.
Some hospitals are treating more patients than ever, and ambulances have been seen queuing with patients at A&E departments across the country.
The College of Emergency Medicine says staff levels are critical.
NHS and Welsh government officials are holding twice-daily conference calls to try and address the problem.
BBC Wales health correspondent Owain Clarke reports from the University Hospital of Wales, Cardiff.
