Footage posted to social media shows the desperate working conditions inside a Gaza hospital battling with chronic fuel shortages, Al Jazeera reports.

The clip, posted to Instagram by Samir Al-Bouji, shows doctors sweating profusely as they perform a surgery at Nasser Medical Complex in Khan Younis, southern Gaza.

“Everything is turned off here. The air conditioning is turned off. No fans,” says a doctor as he demonstrates conditions in the ward. “All the staff are exhausted[ed], they are complaining [about the] high temperature.”

Hospitals in Gaza are warning they will be forced to shut down imminently due to critical fuel shortages, as a result of an Israeli blockade on supplies since March.
