U.S. President Donald Trump can keep his deployment of National Guard troops in Los Angeles, according to a court ruling, as protests against immigration raids look set to enter their second week in the strongest backlash since his return to power in January.

Mayor Karen Bass said Sunday that Los Angeles does not need National Guard troops to bolster city police amid protests against raids by Immigration and Customs Enforcement agents, despite violent incidents.

The National Guard has at times detained protesters in its deployment to Los Angeles, an official said Wednesday, as demonstrations against Immigration and Customs enforcement raids spread to other major cities.
