A 10-day ceasefire announced by U.S. President Donald Trump and agreed on by Lebanon and Israel has started. Barrages of gunshots rang out across Beirut early Friday as residents fired into the air to celebrate the beginning of the truce.  The two neighboring countries held their first direct diplomatic talks in decades on Tuesday in Washington after more than a month of war between Israel and the Iran-backed, Lebanon-based Hezbollah militant group. The truce, if it holds, could boost attempts to extend the ceasefire between Iran, the United States and Israel after weeks of devastating war that killed thousands of people and upended global markets by disrupting the flow of oil.
