Zaki Shaheen, a former Gaza health ministry staffer, has converted his shop into a makeshift medical clinic to help the wounded and ill in the southern border city of Rafah, Al Jazeera reports.

Rafah has been overrun with hundreds of thousands of displaced people fleeing fighting further north. Shaheen said he’s worked in emergency care “my whole life”.

“So we decided to open a medical department and we got help from the health ministry,” he said, noting the goal is to take pressure off of already overburdened hospitals.

“We receive no less than 30 or 40 cases per day, morning to night. I’ll be sleeping then someone comes in with an injury or a burn, so we treat them,” he said.
