WASHINGTON (AP) — The United States is drawing down the presence of people who are not deemed essential to operations in the Middle East due to the potential for regional unrest, the State Department and military said Wednesday.

The State Department said it has ordered the departure of all nonessential personnel from the U.S. Embassy in Baghdad based on its latest review and a commitment “to keeping Americans safe, both at home and abroad.” The embassy already had been on limited staffing, and the order will not affect a large number of personnel.

The department, however, also is authorizing the departure of nonessential personnel and family members from Bahrain and Kuwait. That gives them an option on whether to leave those countries.

Defense Secretary Pete Hegseth also “has authorized the voluntary departure of military dependents from locations” across the region, U.S. Central Command said in a statement. The command “is monitoring the developing tension in the Middle East.”

White House spokeswoman Anna Kelly confirmed the moves.

“The State Department regularly reviews American personnel abroad, and this decision was made as a result of a recent review,” Kelly said.

Tensions in the region have been rising in recent days as talks between the U.S. and Iran over its rapidly advancing nuclear program appear to have hit an impasse. The talks seek to limit Iran’s nuclear program in exchange for the lifting of some of the crushing economic sanctions that the U.S. has imposed on the Islamic Republic. Iran insists its nuclear program is peaceful.

The next round of talks — the sixth — had been tentatively scheduled for this weekend in Oman, according to two U.S. officials, who spoke on condition of anonymity to discuss diplomatic matters. However, those officials said Wednesday that it looked increasingly unlikely that the talks would happen.

President Donald Trump, who has previously threatened to use military force against Iran if negotiations failed, gave a less-than-optimistic view about reaching a deal with Iran, telling the New York Post’s “Pod Force One” podcast that he was “getting more and more less confident about” a deal.

“They seem to be delaying, and I think that’s a shame. I’m less confident now than I would have been a couple of months ago. Something happened to them,” he said in the interview, which was recorded on Monday.

Iran’s mission to the U.N. posted on social media that “threats of overwhelming force won’t change the facts.”

“Iran is not seeking a nuclear weapon, and U.S. militarism only fuels instability,” the Iranian mission wrote.

Iranian Defense Minister Gen. Aziz Nasirzadeh separately told journalists Wednesday that he hoped talks with the U.S. would yield results, though Tehran stood ready to respond.

“If conflict is imposed on us, the opponent’s casualties will certainly be more than ours, and in that case, America must leave the region, because all its bases are within our reach,” he said. “We have access to them, and we will target all of them in the host countries without hesitation.”

Meanwhile, the Board of Governors at the International Atomic Energy Agency was potentially set to vote on a measure to censure Iran. That could set in motion an effort to snap back United Nations sanctions on Iran via a measure in Tehran’s 2015 nuclear deal with world powers that’s still active until October. Trump withdrew from that deal in his first term.

Earlier Wednesday, a statement from the United Kingdom Maritime Trade Operations center, a Mideast-based effort overseen by the British navy, issued a warning to ships in the region that it “has been made aware of increased tensions within the region which could lead to an escalation of military activity having a direct impact on mariners.”

It urged caution in the Persian Gulf, the Gulf of Oman and the Strait of Hormuz. It did not name Iran, though those waterways have seen Iranian ship seizures and attacks in the past.
