A US envoy has returned to Beirut to push for a cease-fire in Lebanon as a food crisis worsens. Lebanese officials have tentatively welcomed a proposal for an Israel-Hezbollah cease-fire, but it's unclear how close they are to reaching an agreement. In the Gaza Strip, the mass looting of aid trucks by armed men has exacerbated an already severe food crisis, causing shortages and soaring prices. The United Nations has reported that armed men stole food and other aid from 98 trucks over the weekend, the largest single incident of its kind since the start of the war.
