Three major U.S. cities indicated that they’re on heightened alert following U.S. military airstrikes targeting Iranian nuclear facilities on June 21.
In an announcement on the night of June 21, President Donald Trump confirmed that the U.S. military carried out bombing missions targeting three facilities, prompting threats from Iranian officials.
Soon after that, the Metropolitan Police Department in Washington issued a similar statement about the Iran–U.S. conflict and stated that it would increase police presence at religious institutions. The law enforcement agency noted that there are no known threats to the nation’s capital city.
Los Angeles Mayor Karen Bass wrote on X that her city is “monitoring any threats to public safety” that may arise.
Outside the United States, the State Department has ordered nonessential personnel and the families of staff at the U.S. Embassy in Lebanon to leave as concerns mount about Iranian retaliation.
In a notice issued on June 22, the department stated that it had taken the step because of “the volatile and unpredictable security situation in the region.”
The notice makes no mention of any potential evacuation flights or other assistance for private Americans wanting to leave Lebanon but states that they should try to use existing commercial services to depart. The United States has already organized several evacuations of American citizens from Israel and is advising American citizens in Iran on how to leave the country.
After the U.S. airstrike that killed Iranian commander Qassem Soleimani in 2020, Iran launched multiple barrages of missiles at U.S. bases in the Middle East, doing minor damage and causing minor injuries to American troops.
Hours after the June 21 bombing, Trump administration officials signaled a willingness to renew talks with Iran and avoid a prolonged war in the Middle East. Defense Secretary Pete Hegseth told reporters late on June 21 that the United States isn’t seeking regime change in Iran, while Vice President JD Vance said during a June 22 interview that the Trump administration doesn’t want “boots on the ground” in Iran.
Before the U.S. bombing mission, Iran and Israel had engaged in a weeklong aerial conflict, with both sides firing missiles at one another, after Israel struck a host of military and strategic sites in Iran a day after a 60-day negotiating period set in April by Trump expired. Israel has stated that it is seeking to dismantle Iran’s nuclear program, which both U.S. and Israeli officials say was intended to produce nuclear weapons.
