DUBAI — Israel and Lebanon agreed to implement a ceasefire to end hostilities, the Trump administration said on Wednesday, in a boost to hopes for a broader deal to end the U.S.-Israeli war on Iran.

Tehran, which had conditioned any deal with the U.S. in part on an end to fighting between Israel and Lebanon, earlier struck Kuwait, damaging its airport and injuring dozens while the U.S. military carried out strikes near the Strait of Hormuz.

The Israel-Lebanon ceasefire is contingent on a complete cessation of fire from the Iran-aligned Hezbollah militia and the evacuation of all its operatives from the South Litani Sector, a joint statement released by the U.S. State Department said following negotiations in Washington.

The two sides had agreed last month to a ceasefire but hostilities had continued. Israel invaded Lebanon in March in pursuit of Lebanese militant group Hezbollah, which fired across the border in support of Tehran.
