The Gaza Health Ministry on Friday said at least 25 people had been killed and another 50 injured in what authorities labeled an Israeli attack on a tent camp in Muwasi, near Rafah city, in the southern Gaza Strip.
The Health Ministry operates under the control of Hamas officials but the United Nations considers the figures published by the ministry broadly reliable.
Eyewitnesses said Israeli forces shelled the camp, in an area just outside an Israeli-designated safe zone and where thousands have fled since Israel launched its Rafah offensive in May.
The Israeli military said the incident was under review but that "there is no indication that a strike was carried out by the IDF [Israel Defense Forces]" inside the humanitarian safe zone.
