Tensions escalated after President Donald Trump called up the National Guard over the objections of state and city leaders.

6:30 p.m.: More than 100 people gathered at the immigration services building and detention center in downtown Los Angeles to protest the raids. DHS officers fired pepper balls at the protesters before the Los Angeles Police Department dispersed the crowd.

The Pentagon’s deployment of about 700 Marines to Los Angeles to help the National Guard respond to immigration protests follows weeks of rapid developments in President Donald Trump’s signature domestic priority for mass deportations.
