Despite urging Palestinians and others caught in Gaza to flee the northern areas, bombings that claimed the lives of yet more civilians—including children—were reported in Khan Younis and the city of Rafah.

The attacks came hours after the IDF's Rear Adm Daniel Hagari called on Gaza’s residents to move south "for your own safety."

Rafah is directly opposite the Egyptian border.

While the Egyptian government has made clear that it refuses to accept large numbers of Palestinian refugees from Gaza, fearful of the political and security repercussions, it has ordered hospitals in northern Sinai and elsewhere to prepare to take in wounded patients from the enclave — as they have during past rounds of fighting. As Israel pummels besieged Gaza, Egypt resists opening up to refugees

“This border is open to take in any injured,” said Diaa Rashwan, head of Egypt’s State Information Service, at a news conference in front of the Rafah crossing Tuesday. He added that the World Health Organization has inspected “all the hospitals and medical facilities” but that “the occupying forces prevent the crossing from the Palestinian side” — a reference to Israel.
