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 and Hezbollah continued their heavy exchange of fire on Monday, causing many schools to close on both sides of the Israel-Lebanon border, even as officials signaled that the two sides appeared to be nearing the first cease-fire since their conflict began last year.

Diplomacy has focused on restoring a ceasefire based on U.N. Security Council Resolution 1701, which ended a 2006 Hezbollah-Israel war. It requires Hezbollah to pull its fighters back around 30 km (19 miles) from the Israeli border, and the regular Lebanese army to deploy into the border region.
