LOS ANGELES, June 11 (Reuters) - U.S. Marines will join National Guard troops on the streets of Los Angeles within two days, officials said on Wednesday, and would be authorized to detain anyone who interferes with immigration officers on raids or protesters who confront federal agents.

California will face off with Washington in court on Thursday over President Donald Trump's deployment of U.S. troops in Los Angeles after demonstrators again took to the streets in major cities to protest Trump's immigration crackdown.

Police and elected officials say the troops and Marines sent by the Trump administration are not properly trained to interact with civilians. A judge will decide whether to limit their duties.
