Donald Trump said leaders of Lebanon and Israel are expected to speak, in what would mark a rare direct contact after more than six weeks of war between Israel and the Iran-backed armed group Hezbollah.

“It has been a long time since the two leaders have spoken, like 34 years. It will happen tomorrow. Nice!” Trump wrote in a social media post late on Wednesday, without specifying which officials would take part or providing further details.

There was no immediate response from the office of Israeli Prime Minister Benjamin Netanyahu or from Lebanese President Joseph Aoun and Prime Minister Nawaf Salam.

The conflict between Israel and Hezbollah escalated following the broader U.S.-Israeli war with Iran. Hezbollah opened fire on March 2 in support of Tehran, triggering an Israeli military offensive in Lebanon just 15 months after the previous conflict between the sides.

Washington has expressed optimism about reaching a deal to end the wider war with Iran, while also pushing for a ceasefire in Lebanon. Israel’s security cabinet met late on Wednesday to discuss the possibility, according to a senior Israeli official.

Both Israeli and Lebanese officials said Netanyahu’s government is under significant pressure from the United States to reach an agreement to halt the fighting.

Despite the diplomatic push, Israel has continued its military campaign. In a video statement, Netanyahu said Israeli forces were still striking Hezbollah positions and were close to “overcoming” the southern Lebanese town of Bint Jbeil.

A senior Lebanese official said Beirut believes Israel is seeking to secure a military victory in Bint Jbeil before making progress in negotiations.
