BEIRUT, Nov 19 (AP/UNB) - A United States envoy returned to Beirut on Tuesday, where Lebanese officials have tentatively welcomed a proposal for an Israel-Hezbollah cease-fire. There was no such optimism in the Gaza Strip, where the mass looting of aid trucks by armed men worsened an already severe food crisis.
 
Amos Hochstein, the Biden administration's pointman on Israel and Lebanon, arrived as Hezbollah's allies in the Lebanese government said it had responded positively to the proposal, which would entail both the militants and Israeli ground forces withdrawing from a U.N. buffer zone in southern Lebanon.
 
It's unclear how close they are to clinching an agreement. The buffer zone would be policed by thousands of additional U.N. peacekeepers and Lebanese troops. Israel has called for a stronger enforcement mechanism, potentially including the ability to operate against any Hezbollah threats, something Lebanon is likely to oppose.
 
In Gaza, meanwhile, the theft of nearly 100 trucks loaded with food and other humanitarian aid over the weekend sent prices soaring and caused shortages in central Gaza, where most of the population of 2.3 million people have fled and where hundreds of thousands are crammed into squalid tent camps.
 
An even more severe hunger crisis is underway in the north, where Israel has been waging a weekslong offensive that has killed hundreds of people and driven tens of thousands from their homes. Experts say a famine might already have set in there.
