What's blocking a ceasefire between Israel and Hezbollah?

Diplomats and other officials say there have been several sticking points in ceasefire talks in the war between Israel and the Lebanese militant group Hezbollah, even as conditions for an agreement appear to be ripe. Israel’s military has killed nearly all of the militant group’s top leaders. Tens of thousands of Israelis who were evacuated from the border months ago are pressuring their government to go home. And the world wants to stop regional conflict from spreading after more than a year of fighting. But there remain sticking points over how Hezbollah’s withdrawal from the border area will be monitored and whether Israel will have freedom to strike the militants.
