UN Secretary-General Antonio Guterres is expected to visit Egypt's border with Gaza on Saturday, after Israel said it would send in troops to fight Hamas in the nearby city of Rafah, even without US support.
During his visit, Guterres plans to reiterate his call for a humanitarian ceasefire, though renewed international pressure has so far failed to dissuade Israel from the planned ground offensive in Rafah, where most of Gaza's population has taken shelter.
