Israel hit Gaza with air strikes on Tuesday as world powers grappled with how to broker a ceasefire ahead of a UN Security Council vote that was expected to be blocked by a US veto. A total of 103 Palestinians were killed in the past 24 hours of Israeli strikes and ground combat in the besieged Hamas-ruled territory, its health ministry said. The United Nations has sounded the alarm over the dire humanitarian situation in Gaza, warning that food shortages could lead to an "explosion" of preventable child deaths. More than four months of relentless fighting have flattened much of the coastal territory, pushed 2.2 million people to the brink of famine and displaced three-quarters of the population, according to UN estimates. For in-depth analysis and a deeper perspective on the Israel-Hamas war, Israel's war-time military strategy, the relentless ground invasion eying Rafah and the harrowing plight of civilians in war-torn Gaza, FRANCE 24's Mark Owen is joined by Dr H A Hellyer, Senior Associate Fellow at the Royal United Services Institute (RUSI).
