TEL AVIV, Israel (AP) — President Joe Biden will travel to Israel on Wednesday to show support for the U.S. ally as concerns increase that the raging Israel-Hamas war could expand into a larger regional conflict.

U.S. Secretary of State Antony Blinken announced Biden’s travel to Israel as the humanitarian situation in the Gaza Strip grows more dire and as Israel prepares for a possible ground attack on the 141-square-mile territory to root out Hamas militants responsible for what U.S. and Israeli officials say was the most lethal assault against Jews since the Holocaust.
