Israeli Prime Minister Benjamin Netanyahu has vowed to invade the southern Gaza city of Rafah, despite international opposition. He claims Rafah is Hamas' last stronghold in Gaza and believes a ground operation there is essential for victory. However, the international community, including the US, warns that the operation could endanger the roughly 1.4 million civilians seeking shelter in Rafah. Israel insists it has a plan to protect civilians. Netanyahu's statement comes as Israeli negotiators discuss cease-fire efforts with Hamas in Cairo.
