SAN FRANCISCO (AP) - The mayor of Los Angeles is urging demonstrators to "practice peace" after protesters upset by the acquittal of George Zimmerman in the shooting of Trayvon Martin clashed with police and blocked traffic on a freeway and city streets.
Mayor Eric Garcetti issued the call for peace on Twitter Sunday night after groups of people broke off from a peaceful march and threw rocks and batteries at officers. Officers responded by firing nonlethal beanbag rounds, and arrested one man.
Other groups blocked traffic by walking onto busy Interstate 10, and to a Hollywood intersection where they waved signs bearing the photo of the slain black teen.
Police officials said they were monitoring the protests and waiting for the group to disperse.
