Israel has cut off the entry of all food and other goods into Gaza in an echo of the siege it imposed in the earliest days of its war with Hamas

Hamas accused Israel of trying to derail the ceasefire agreement hours after its first phase ended. It called the decision to cut off aid “cheap extortion, a war crime and a blatant attack” on the truce, which took hold in January after over a year of negotiations. Both sides stopped short of saying the ceasefire had ended.

Israel blocked aid trucks into Gaza as a cease-fire standoff has escalated, with Hamas calling on other mediators to intervene.
