Trayvon Martin death: US protests over Zimmerman verdict

Protests have taken place across the US after neighbourhood watch volunteer, George Zimmerman, was cleared of murdering an unarmed black teenager.

Most demonstrations were peaceful, demanding justice for the family of 17-year-old Trayvon Martin and questioning the fairness of the justice system.

The biggest protest was in New York, where a small rally grew into a crowd of thousands.
