NI ambulance crisis could happen again 

Medical staff return a bed to an ambulance at Antrim Area Hospital, Co Antrim in Northern Ireland.

A doctor in charge at the Northern Ireland hospital which saw 17 ambulances queued up outside on Tuesday said it is impossible to guarantee this will not happen again as the Covid-19 crisis deepens.

Cases of coronavirus in Northern Ireland have been increasing with a six-week lockdown now announced for December 26 as 510 new daily cases were confirmed on Friday.
