At least 64 Palestinians have been killed by Israel since dawn, with 42 of them dying in besieged Gaza City, medical sources tell Al Jazeera.

As of Wednesday afternoon, Al-Shifa Hospital and Al-Ahli Hospital in Gaza City reported 17 and 25 deaths, respectively. Nasser Hospital in southern Gaza said the Israeli army killed another 16 people.

The latest killings come a day after UN chief Guterres said the “scale of death and destruction” in Israel’s onslaught on Gaza was beyond any other conflict he has seen during his tenure.
