As Joe Biden arrived in Israel today, anger boiled over across the region after a Gaza hospital was hit last night. Israel and the United States say it was a failed rocket launch by Palestinian militants, but Palestinian officials immediately blamed Israel, prompting street protests from Lebanon to Tunisia and Arab leaders to cancel face-to-face meetings with Biden. Martin Griffiths is Emergency Relief Coordinator for the United Nations and joins Christiane from Cairo, where he has been meeting with Egyptian officials.
