The Israel Defense Forces said in a post to X on Monday that it had launched "a widespread wave of attacks" against Iranian government infrastructure in the capital Tehran.

In a notice on the U.S. State Department official website, the agency is advising Americans worldwide, "and especially in the Middle East," to "exercise increased caution."

"Americans abroad should follow the guidance in security alerts issued by the nearest U.S. embassy or consulate," the statement reads.

The State Department is warning that U.S. diplomatic facilities, including those outside of the Middle East, "have been targeted."

The agency warns that groups in support of Iran "may target other U.S. interests overseas or locations associated with the United States and/or Americans throughout the world."

Officials in Abu Dhabi said in a statement that one person was injured due to falling debris from a missile attack in the Al Shoamkh area.

UAE air defences responded to incoming missile and drone threats from Iran, officials said.

The Israel Defense Forces said in a statement that it's planning to "deepen" its military actions against Hezbollah in Lebanon.

"We are now preparing to deepen the maneuver and strikes according to an orderly plan. We will not stop until the threat is removed from the borders and long-term security is ensured for the residents of the northern region," the IDF said.

"It is a long battle, and we are prepared for it," the IDF added.

Further details about the operation were not provided.

Energy Secretary Chris Wright elaborated on the possibility of the U.S. lifting sanctions on Iranian oil already out at sea, dismissing concerns of Iran profiting from the move by arguing that the oil was “going to be monetized anyway," in a Fox News appearance Friday morning,

Asked how the administration justifies Iran monetizing oil amid the ongoing conflict. Wright insisted that the oil would have been “monetized other ways,” regardless of U.S. potentially lifting sanctions, and he echoed Treasury Secretary Scott Bessent’s comments on Thursday that suggested Iranian oil would have been going to China.

This would be a major reversal in U.S. policy, which has sanctioned Iranian oil for decades. And – in the middle of the war – it would mean Iran stands to make more money by selling its oil to the highest bidder.

Bessent floated the possibility of this move on Fox Thursday.

Regarding the expected timeline of unsanctioned oil becoming usable supply, Wright was confident that this would happen “pretty quickly.”

“Well, with un-sanctioning, I mean within days, within three or four days that oil will start to arrive in ports and of course most refineries are near ports. So pretty quickly,” he said.

Wright also said he believes most of the unsanctioned oil would “be absorbed in the next 30 to 45 days.”

Asked about some projections that predict oil to rise beyond $180 a barrel if disruptions persist until late next month, Wright pivoted to slam the Iran’s retaliatory attacks, saying “this destruction certainly is not helpful for global oil prices” before arguing that that this further justifies the need for the U.S. military to “finish the job.”
