Secretary of State Rubio said the agreement reached Friday between Israel and Lebanon "begins to put in place a framework for lasting peace and security."

He thanked the people in the room for their work but acknowledged there was still a long road ahead of them.

"As I told all the parties here today, it's the beginning of the beginning. There's a lot of work ahead," Rubio said at the State Department. "We don't in any way underestimate the difficulty of the task ahead, but we understand the importance of it, how vital it is."

Rubio held calls with Israeli Prime Minister Benjamin Netanyahu and Lebanese President Joseph Aoun to get the framework agreement over the finish line and joined the talks in person Friday morning, according to a U.S. official.

The agreement is expected to include immediate action by both sides, including limited withdrawals from Israeli forces.

Despite the signing of the agreement, there is still no guarantee that Hezbollah will abide by its terms.

A framework agreement between Israel and Lebanon is expected to be signed Friday night in Washington, an Israeli source familiar with the matter told ABC News.

Representatives of Israel and Lebanon made significant progress on the fourth day of talks on Friday, according to two sources familiar with the developments. Both sides agreed to a ceasefire framework in early June, according to the sources.

President Donald Trump said Friday that Iran shot "at least four" one-way attack drones at ships crossing through the Strait of Hormuz.

One of the drones damaged a cargo ship while the U.S. shot down three others, Trump said on social media, calling the actions a "foolish violation" of the ceasefire agreement.

The president did not say when the four drones were shot -- though he appears to be addressing the vessel struck by Iran in the Strait of Hormuz on Thursday.

Iran’s state-run Press TV reports that a direct communication line has been established between Iran and the United States in the Strait of Hormuz on Friday. The direct channel is apparently intended to help prevent incidents that could escalate into military confrontation, according to the Iranian state TV.

Iranian state media is also reporting that three foreign oil tankers were turned back in the Strait of Hormuz after encountering warnings from the Iranian Navy on Friday.

The tankers were reportedly attempting to "illegally" transit the Strait of Hormuz and use the Southern Corridor. The tankers then changed course to the Persian Gulf, according to Iranian state TV.

The U.S. has not immediately commented about these claims.
