BBC – The resumption of fighting between Israel and Hamas has been met with a mixture of fear and anger in Gaza, with the UN calling it a “nightmare”.
A temporary ceasefire expired at 07:00 (05:00 GMT) with both warring sides blaming each other.
Since then, Gaza’s Hamas-run health ministry says 178 people have been killed in Israeli attacks.
A UN official said much-needed aid had stopped coming through the Rafah crossing since the ceasefire ended.
On Friday morning, the sound of heavy gunfire could be heard in areas of northern Gaza infiltrated by the Israeli military, with clashes breaking out between Israeli soldiers and Hamas fighters.
