AUSTIN, Texas — Protests over federal immigration enforcement raids are flaring up around the country, as officials in cities from coast to coast get ready for major demonstrations against President Donald Trump over the weekend.

While many demonstrations against the Immigration and Customs Enforcement agency have been peaceful, with marchers chanting slogans and carrying signs, others have led to clashes with police who have sometimes used chemical irritants to disperse crowds. Hundreds have been arrested.

Volatile protests prompted city officials to enforce curfews in Los Angeles and Spokane. And in Texas, Republican Gov. Greg Abbott has mobilized more than 5,000 National Guard troops to be ready to help law enforcement manage demonstrations in his state.

Activists are planning “No Kings” events across the country on Saturday to coincide with Trump’s planned military parade in Washington, D.C. While those were already scheduled, they will happen amid the rising tensions of the week.

The Trump administration said immigration raids and deportations will continue regardless.

A look at some recent protests and reactions across the country:

Seattle

Hundreds of protesters marched through downtown Seattle Wednesday evening to a federal building where immigration cases are heard. Some of them dragged a dumpster nearby and set it on fire. The building was covered in graffiti, with “Abolish ICE Now” written in large letters across its front window. They moved electric bikes and cones to block its entrance.

San Antonio

Several hundred protesters marched through downtown San Antonio and near the historic Alamo mission. Although Texas National Guard troops were seen in the area, the demonstration was mostly peaceful with no significant clashes with law enforcement.

The Alamo building and plaza, among the most popular tourist attractions in the state, was closed to the public early and police guarded the property as the crowd gathered and marched nearby.

‘No Kings’

This week’s protests are leading into the scheduled “No Kings” demonstrations that organizers say are planned in nearly 2,000 locations around the country, from city blocks to small towns, courthouse steps to community parks, according to the movement’s website.

Organizers plan a flagship march and rally in Philadelphia, but no protests are scheduled to take place in Washington, D.C., where the military parade will be held.

In Florida, state Attorney General James Uthmeier warned that any “No Kings” protesters who become violent will be dealt with harshly.

Governors and the Guard

Several “No Kings” rallies are planned in Texas, including in San Antonio, Houston, Dallas and Austin. There were brief clashes between protesters and police who used chemical irritants during demonstrations in Austin and Dallas earlier in the week. Police in Austin made about a dozen arrests.

Abbott did not detail where he was sending the 5,000 guard troops and another 2,000 state police, or exactly what they would do except to say they would be ready to help local law enforcement as needed. Mayors in San Antonio and Austin have said they have not asked for help from the National Guard.
