Hundreds of U.S. Marines arrived in Los Angeles overnight and more were expected on Tuesday under orders from President Donald Trump, who has also activated 4,000 National Guard troops to quell protests despite objections from California Governor Gavin Newsom and other local leaders, Reuters reported.

The city has seen days of public outrage since the Trump administration launched a series of immigration raids on Friday, though local officials said the demonstrations on Monday were largely peaceful.

About half of the roughly 700 Marines that Trump ordered to Los Angeles arrived on Monday night, and the remaining troops will enter the city on Tuesday, a U.S. official told Reuters. The U.S. military did not immediately respond to a request for comment.

Los Angeles Mayor Karen Bass told KABC that more than 100 people had been arrested on Monday but that the majority of protesters were nonviolent. Over the weekend, protesters threw rocks and other objects at officers and vehicles and set several cars ablaze. Police responded by firing projectiles like pepper balls as well as flash bang grenades and tear gas.

Trump has justified his decision to deploy active military troops to Los Angeles by describing the protests as a violent occupation of the city, a characterization that Newsom and Bass have said is grossly exaggerated.
