Dr Hussam Abu Safia, the director of the besieged Kamal Adwan Hospital in Beit Lahiya, has renewed an appeal for global intervention in a letter published in English on Telegram, Al Jazeera reports.

“We are speaking from the centre of the intensive care unit, the only one in the northern Gaza Strip, after enduring over fifty days of siege,” he wrote.

“After the failure of the occupying army to evacuate the north, they have now begun to directly target our healthcare system […] For the past seven consecutive days, we have been bombed directly,” he said.

These include attacks on the hospital’s reception, emergency departments, the electricity generators, the oxygen station and the water network, he said.

The doctor, who was also wounded in an Israeli attack, said, “Everyone here is at risk” and accused Israeli forces of using a new type of weapon against people at the facility.

“Specifically a quadcopter that drops bombs containing tiny fragments that are nearly invisible to the naked eye. These projectiles penetrate the bodies of our workers, causing severe bleeding and damage to internal organs,” he said.

Israeli forces are waging a “campaign of extermination” in northern Gaza, he said. “Once again, we urgently call on the world to stop the bloodshed occurring in the northern Gaza Strip.”
