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.

President Donald Trump in a social media post late Wednesday night, called for Israel to not attack the South Pars Gas Field unless Iran again attacks Qatar's liquefied national gas facilities.

“NO MORE ATTACKS WILL BE MADE BY ISRAEL pertaining to this extremely important and valuable South Pars Field unless Iran unwisely decides to attack a very innocent, in this case, Qatar,” Trump said.

Trump said if Iran does so, the U.S. will respond and “massively blow up” the South Pars gas field.

"I do not want to authorize this level of violence and destruction because of the long term implications that it will have on the future of Iran, but if Qatar’s LNG is again attacked, I will not hesitate to do so," Trump said in the post.

Trump began his post saying the U.S. was not made aware in advance of Israel’s attack on South Pars on Wednesday, an escalation in the conflict.

Trump also claimed that Qatar was also not aware Israel would strike the Iranian gas field.

“The United States knew nothing about this particular attack, and the country of Qatar was in no way, shape, or form, involved with it, nor did it have any idea that it was going to happen,” Trump wrote.

Iranian state media said Wednesday that Israel attacked Iran’s South Pars Gas Field, one of the nation’s largest gas resources and a key lifeline for Iran.
