Vigils planned for 100 cities over shooting verdict

Vigils and rallies will be held in 100 US cities this weekend to press for federal civil rights charges against George Zimmerman over the shooting of unarmed teenager Trayvon Martin.

The prominent civil rights activist Rev Al Sharpton announced the plan outside the Justice Department in Washington.

He did not say which cities would be involved, but did say the rallies and vigils will be staged on Saturday at federal buildings.
