The Rafah crossing – the sole entry point between Egypt and Gaza – remains a political, diplomatic and humanitarian tinderbox. While Egypt has kept the border firmly closed to Gazan refugees fleeing from the Israel-Hamas war, it has allowed an aid corridor for several dozen trucks delivering food, water and medical supplies.
