The ceasefire between Israel and Hezbollah took effect at 4 a.m. local time on Wednesday, but experts remain skeptical about its viability.

President Joe Biden announced Tuesday that Israel and Hezbollah had agreed to a 60-day ceasefire, including the withdrawal of Israeli ground forces from Lebanon and the withdrawal of heavy Hezbollah weapons north of the Litani River. It reflected the same deal that ended the 2006 Israel-Hezbollah War, though Hezbollah quickly broke the terms that time around. This deal allows for better enforcement by the Lebanese military and a panel of five countries, led by the United States.
