Israel has cut off the entry of all food and other goods into Gaza, sparking sharp criticism from the United Nations and other humanitarian aid providers. The decision is seen as a violation of international law and has raised concerns about hunger and possible famine in the region. Israel is trying to pressure Hamas to agree to a U.S. proposal to extend the ceasefire's first phase instead of starting negotiations on the more difficult second phase. Aid organizations have repeatedly criticized Israeli restrictions on items entering Gaza, while Palestinians have reported limiting meals and foraging for food. The sudden aid cutoff has led to a surge in prices and has been condemned as a violation of international humanitarian law.
