Health authorities in Gaza have said Israeli forces surrounded and shelled the Indonesian Hospital in the territory’s northern town of Beit Lahia at dawn, 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 had 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.
