President Biden landed in Israel on Wednesday, making an audacious visit to a region seething with anger and recriminations after a blast at a hospital in the Gaza Strip that Palestinian officials said killed hundreds of people, and left Palestinians and Israelis trading blame.
Protests broke out in cities across the Middle East in response to the explosion, further inflaming a region that is worried about a broader war breaking out. A scheduled meeting in Jordan between Mr. Biden and Arab leaders was canceled, as key allies in the region condemned the explosion.
