The US Marines are being mobilized in response to protests in Los Angeles, with approximately 700 Marines joining the 1,700 National Guard members already deployed. The deployment is seen as a significant escalation in the use of military force against protesters. The Marines' specific tasks have not been publicly specified, but they are prohibited from conducting law enforcement activities unless the Insurrection Act is invoked. The move has been met with criticism from California Governor Gavin Newsom, who described it as 'unwarranted' and 'unprecedented'.
