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.

Israeli airstrikes killed a hospital director at his home in northeastern Lebanon and six others, while at least five paramedics were killed by Israeli strikes in the country's south on Friday, Lebanon's Health Ministry said.

Scores of people were killed overnight in Israeli airstrikes on houses in northern Gaza where displaced people were sheltering, according to media reports and agencies run by Gaza's Hamas-led administration.
