President Donald Trump is trumpeting the "great deal" he has made with Iran, claiming it will bring "peace and security" to the entire region.

He also confirmed the deal will be signed on Friday, claiming that oil will flow from "both ends of the region" after the Strait of Hormuz is opened when the agreement is signed. The oil flow is linked to mine removal, he claims.

"With the opening of the Strait upon the signing of the Deal on Friday, for purposes of mine removal, oil will flow on both ends again for the Region, and the World!" Trump wrote on his social media platform.

President Donald Trump said in a post on social media Sunday that the United States and Iran have reached a deal, opening up the Strait of Hormuz.

"I hereby fully authorize the toll free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States Naval blockade," Trump wrote.

"Ships of the World, start your engines. Let the oil flow!" he added.

Iranian Deputy Foreign Minister Kazem Gharibabadi confirmed the deal had been finalized and said it would be signed in Switzerland on Friday.

"All of our positions and important issues are included in the draft understanding," Gharibabadi said in a statement to Iranian state media.

The U.S. and Iran's comments came after Pakistan Prime Minister Shehbaz Sharif announced the peace deal was made. "Both sides have declared the immediate and permanent termination of military operations on all fronts, including in Lebanon," Sharif wrote.

The Israeli military announced on Sunday that it had killed a senior Hezbollah commander in a "precise strike in southern Lebanon."

Israeli military officials said the Hezbollah commander, identified as Ali Musa Daqduq, was killed south of the Litani River on Friday.

Israel Defense Forces (IDF) said Daqduq held a series of senior positions within the Hezbollah terrorist organization and served "as a source of knowledge with extensive operational experience."

"His elimination constitutes another significant blow to Hezbollah’s senior chain of command by eliminating one of the most prominent operatives responsible for terrorist activity against Israeli civilians, IDF soldiers, and American service members," the IDF alleged in a statement.

In recent years, the IDF said Daqduq played a central role in advancing terrorist attacks and combat operations against Israel and IDF soldiers.

The Israel Defense Forces said in a post to X on Sunday that it conducted a new strike on the Lebanese capital Beirut, targeting what it called Hezbollah "infrastructure" in the southern Dahiyeh area of the city.

In a statement, Israeli Prime Minister Benjamin Netanyahu said the strike was "in response to Hezbollah's firing into Israeli territory. Israel will not tolerate firing into its territory."

President Donald Trump told Axios that after Iran and Israel traded strikes Sunday night for the first time since the U.S. and Iran agreed to a ceasefire in April, he warned Israeli Prime Minister Benjamin Netanyahu that he might be “on [his] own very soon” if war resumed.

"I said, 'Bibi, you better be careful, or you will be on your own very soon,'" Trump said in a phone interview on Monday.

Axios reported that Trump called Netanyahu on Sunday evening and asked him not to retaliate against Iran after they launched attacks at Israel.

Trump claimed in the interview with Axios that Israel "gave us very late notice" about Sunday's strikes.

"They were already on their way. But eventually I had [the Israeli strike] limited," Trump said.

Trump also told Axios he received calls from five different countries in the region asking him to press Netanyahu to stop.

"These countries were very concerned. They love the deal that we have been negotiating," Trump said.

Trump also claimed his administration received messages from the Iranians on Monday morning stating a willingness to stop shooting if Israel did the same.

"They called us and said that they are not doing any more attacks and asked us to tell Israel not to do any more attacks," Trump said.
