Israel is open to ideas for de-escalating the conflict in Lebanon, Israel's U.N. Ambassador Danny Danon said on Tuesday, a day after the United States said it was exploring some "concrete ideas" with allies and partners.

President Joe Biden says all-out war is still possible as fighting between Israel and Hezbollah escalates, but he's hopeful an off-ramp can be found to prevent further bloodshed.

Israel killed two workers for the UN Refugee Agency, the agency has said, in bombardments across Lebanon on Monday that resulted in the deadliest single day of attacks in the country in decades.
