Last week, prior to the ground incursion, Israel was criticized for an aerial bombardment of a rocket launcher in Gaza City's Saja'iyya neighborhood. The IDF said then that the launcher was in an empty structure adjacent to el-Wafa Rehabilitation Hospital.
Hours before the strike the hospital received an automated phone message from the IDF saying its staff had to evacuate all patients as they could get hurt in the strike.
But the hospital staff and its director said they could not evacuate the elderly and disabled patients who were having a hard time moving. Hospital director Basman Elashi told Yedioth Ahronoth then that he decided to move the patients to the first floor. According to him, the hospital's top floors were hit.
"The strike was on an unpopulated structure that used to serve as the hospital's geriatric ward," he said.
International media crews rushed to the scene to report the attack to the world.
Elashi said he was unfamiliar with the IDF claims a rocket launcher was stashed in the building.
"The army's leaning on bad information here," he said. "I've never seen any installation of a rocket launcher near the hospital."
He denied reports Hamas had demanded him not to evacuate the hospital, but other sources said Hamas sent people into the hospital to serve as human shields.
