France's intensive care units (ICU) are heading towards saturation point.
The country is struggling to bring its coronavirus epidemic under control, reporting another 58,000 new infections on Thursday.
That is the highest daily caseload since the pandemic began.
Fewer than a third of ICU beds left
Announcing the figures, the country's health director-general Jerome Solomon warned the country's second wave of COVID-19 "is brutal and spreading quickly".
Nurses and doctors are under tremendous pressure all over France.
There are currently around 4,000 COVID-19 patients in intensive care units. Hospitals have around 1,800 places left.
