Gaza health officials said Israeli forces surrounded and shelled the Indonesian Hospital in the territory’s northern town of Beit Lahia at dawn, while the military reported troops were operating near the facility, AFP reports.

“Israeli tanks have completely surrounded the hospital, cut off electricity and shelled the hospital, targeting the second and third floors with artillery,” said the facility’s director, Marwan Sultan. “There are serious risks to medical staff and patients.”

In a statement, Gaza’s health ministry also said Israel targeted the upper floors, adding there were “more than 40 patients and wounded in addition to the medical staff” present. “Heavy gunfire” towards the hospital and its courtyard had sparked a “state of great panic” among patients and staff, it added.

Contacted by AFP, the Israeli military said its troops were operating near the Indonesian Hospital. “The troops operating in the area have been trained for the operational activity and briefed on the importance of mitigating harm to civilians and medical infrastructure,” the military said in a statement to AFP.
