Israel on Friday approved a potential assault on the Gaza city of Rafah while also keeping cease-fire hopes alive with plans to send another delegation to Qatar for talks on a possible hostage deal with Islamist militant group Hamas.

Israeli Prime Minister Benjamin Netanyahu's office said he had OK'd a plan to attack the city on the southern edge of the shattered Palestinian enclave where more than half of its 2.3 million residents are sheltering after five months of war.

Global allies and critics have urged Netanyahu to hold off attacking Rafah, fearing mass civilian casualties. But Israel says it is one of the last strongholds of Hamas whom it has pledged to eliminate and that residents will be evacuated.
