BEIRUT — A hospital in southern Lebanon said in a statement that it had been shelled by Israeli forces Friday after being warned to evacuate. The statement from Salah Ghandour Hospital in the town of Bint Jbeil said the shelling “resulted in nine members of the medical and nursing staff being injured, most of them seriously,” while most of the medical staff were evacuated. A day earlier, the World Health Organization says 28 health workers in Lebanon had been killed in the past 24 hours. Earlier on Friday, the Israel military in a statement alleged that rescue vehicles were being used by Hezbollah to transport militants and weapons.
