A woman in a "Make America Great Again" hat leads a chant for "regime change" in Iran.

The crowds dance and wave Iranian, Israeli and American flags as Persian music blasts. Car horns beep in support but also some annoyance in LA's gridlocked traffic.

Protests outside the West LA Federal Building are a common site, but even by LA standards this one is unusual, happening under the watchful eyes of armed US Marines, controversially ordered there by President Trump during protests against immigration raids.

But these immigrants are proudly demonstrating in MAGA hats in support of President Trump and his decision to intervene in the Israel-Iran conflict by launching air strikes against Iranian nuclear sites.

"We want regime change in Iran," says Bita Ashrafi, who left Iran 50 years ago and attended the protest wearing a "Trump Was Right About Everything" hat.
