Attacks, which killed women and children, come day before border crossing is due to open in Gaza’s southern most city

Israel has carried out some of its deadliest airstrikes on Gaza in months, killing at least 30 Palestinians, some of whom were sheltering in tent cities for displaced people.

Despite a nominal ceasefire, the Israeli military struck a police station in the Sheikh Radwan neighbourhood west of Gaza City on Saturday, killing 10 officers and detainees, the civil defence said, who indicated the death toll could rise as emergency responders searched for bodies.
