U.S. President Donald Trump on Monday urged residents of Tehran to evacuate, amplifying warnings from Israeli Prime Minister Benjamin Netanyahu as Israel launched a large-scale assault on Iran.

“Everyone should immediately evacuate Tehran!” Trump posted on his Truth Social platform during the Group of Seven summit in Canada.

Trump did not provide further details. Tehran, Iran’s capital, is home to nearly 10 million people.

The warning follows intensified Israeli strikes targeting what it claims are Iranian nuclear facilities. Earlier, the Israeli military issued an evacuation advisory to residents of a district in Tehran — a move reminiscent of its tactics in Gaza since the October 7, 2023 attacks.

While Trump has stopped short of confirming U.S. military involvement, he told reporters at the G7: “As soon as I leave here, we’re going to be doing something. But I have to leave here.”
