President Joe Biden has arrived in Tel Aviv to demonstrate U.S. solidarity with Israel ahead of an expected ground assault against Hamas. During a meeting with Prime Minister Benjamin Netanyahu, Biden expressed sadness and outrage over a deadly blast at a hospital in Gaza City, suggesting Palestinian militants were behind it. Biden is expected to meet with Israeli and Palestinian leaders during his trip, and his visit is seen as an effort to show U.S. support for Israel and to prevent the war from escalating.
