By Brad Brooks, Phil Stewart, Idrees Ali and Dietrich Knauth LOS ANGELES (Reuters) -Hundreds of U.S. Marines arrived in the Los Angeles area on Tuesday under orders from President Donald Trump, as the city's mayor declared a curfew for parts of the downtown area and police arrested 197 people in a fifth day of street protests.

The protests began Friday after Immigration and Customs Enforcement agents carried out coordinated raids across Los Angeles, detaining dozens of workers at warehouses and other worksites. The arrests sparked immediate backlash, with demonstrators converging outside federal buildings, blocking freeways, and in some cases clashing with police.

Six Americans tell the BBC that there's clearly a problem in Los Angeles - they just don't agree with who's at fault.

President Donald Trump has built his presidency around stretching the bounds of presidential authority, and his response to protests over an immigration crackdown in Los Angeles is no exception.

Tensions flared in Los Angeles late Monday. On Tuesday, teams worked to scrub away, cover up or fade out protesters' graffiti.

Protests in Los Angeles appeared to quiet overnight, but new ones are popping up in other cities. Trump has deployed more than 4,000 National Guard troops and 700 Marines to the protests.

California Attorney General Rob Bonta said Monday that he’ll soon file a lawsuit against the Trump administration for federalizing National Guard troops this weekend.

Authorities swept in with flash-bangs and tear gas grenades to disperse hundreds of protesters in Los Angeles.
