A small number of Palestinians from Gaza have started crossing into Egypt for medical treatment after Israel allowed a limited reopening of the Rafah border crossing. It had been largely closed since Israeli troops seized it in May 2024, cutting off a critical lifeline for those in Gaza. Around 20,000 Palestinians needing medical care hope to leave Gaza using the crossing, but only a handful have been allowed through so far. The reopening of Rafah is seen as a key step in the US-brokered ceasefire agreement as it moves into its second phase. Lucy Hough speaks to chief Middle East correspondent Emma Graham-Harrison
