Health officials in the Hamas-run enclave said eight Palestinians were killed and dozens of others wounded in an Israeli strike that hit the Al-Tabeaeen School, which was sheltering displaced families in Gaza City. Among those killed were two sons of former Hamas spokesman, Fawzi Barhoum, according to medics and Barhoum himself.

At Kamal Adwan Hospital, one of three medical facilities on the northern edge of Gaza that is barely operational, director Hussam Abu Safiya said the ongoing Israeli bombardment appeared aimed at forcing hospital staff to evacuate - something they have refused since the incursion began.

Gaza authorities on Sunday reported that Israel has killed more than 1,000 doctors and nurses in the besieged Palestinian territory since October of last year.
