US Defence Secretary Lloyd Austin is expected to press Israel to wind down major combat operations in Gaza during his visit. Israel's closest allies, including France, the UK, and Germany, have joined global calls for a cease-fire. Israeli protesters are demanding talks with Hamas on releasing more hostages after three were killed by Israeli troops. The war has killed over 18,700 Palestinians and displaced 1.9 million people. The US has provided support to Israel while urging greater efforts to avoid civilian casualties.
