This week has seen US immigration authorities carry out raids and crackdowns in Democrat-voting Los Angeles.
The tally of arrests of undocumented immigrants has climbed past 100 people as Donald Trump looks to make good on one of his key election promises.
However, during some of the raids, some protesters sought to block border patrol vehicles, pelting them with rocks.
In response, federal agents in riot gear used tear gas, flash bangs and pepper balls.
Following these clashes, protests began Friday in downtown Los Angeles, before spreading Saturday to Paramount, a heavily Latino city south of LA, and neighbouring Compton.
Trump then ordered the deployment of 2,000 National Guard troops on Sunday in an unprecedented move, going over the head of governor Gavin Newsom.
With tensions ratcheted up, a political back-and-forth is ongoing as today could see more unrest.
