The State Department is reducing staffing at four US embassies in the Middle East after receiving intelligence that Iran has stepped up efforts to target American personnel in the region and elsewhere.
In a memo sent Friday to Secretary of State Marco Rubio, Director of National Intelligence Jay Clayton said his teams "have received intelligence that Iran has substantially increased efforts to target US personnel."
"The lethal plotting efforts by the Iranians against US citizens have reached advanced stages in both the Middle East and certain other countries," Clayton wrote.
The memo was obtained by The Associated Press and reported earlier by Axios. Three US officials, speaking on condition of anonymity due to the sensitivity of the matter, confirmed that the memo was sent to Rubio in his capacity as secretary of state and national security adviser.
The memo emerged shortly after the State Department announced it is reducing staff at the US embassies in Jordan, Lebanon, Qatar and the United Arab Emirates. The three officials said the threats from Iran and Yemen's Iranian-backed Houthi rebels are related to the staffing changes.
The embassies involved are all under what is known as "restricted operations" status that has already reduced the size of their personnel footprints. The embassies will remain open.
However, unlike in Saudi Arabia, where nonessential US personnel and their families were ordered Wednesday to leave the country, staff in the other four countries are not compelled to depart.
In announcing the staffing drawdowns this week, the State Department pointed specifically to increased threats from Yemen's Houthi rebels and did not mention threats to US personnel directly from Iran. There has been a resurgence of fighting between a Saudi-led coalition and the Houthis, with the militant group launching missile and drone strikes against Saudi Arabia.
US officials have adamantly denied the drawdowns are tied to any potential new US and Israeli strikes on Iran. The unpopular war has spiked energy costs for Americans and posed political problems for President Donald Trump and Republicans, who are trying to keep control of Congress in the November 3 midterm elections.
Trump, speaking at a rally Friday in Florida, touted the US military operations in Iran, which were dubbed "Operation Epic Fury," and said that "we may do another little Epic Fury, or they'll agree. If they're smart, they'll just say, Let's get down to business."
Mediators have been trying to bring Washington and Tehran back to formal talks as the war has reached a stalemate.
According to Iranian state television, the Revolutionary Guard navy this week again threatened to strike US military bases in the region if the United States keeps helping guide commercial ships through the Strait of Hormuz, a critical waterway for the global energy trade.
"Any further escalation around the Strait of Hormuz or elsewhere in the region will put civilian lives and the well-being of all regional states and the global economy at great risk," Iranian Foreign Minister Abbas Araghchi wrote in an opinion column in the Financial Times this week.
