Trayvon Martin: Protests at George Zimmerman verdict

Protests over the not guilty verdict for a man accused of killing an unarmed black teenager in Florida are taking place across the US.

Lawyers for George Zimmerman, 29, successfully argued that he was acting in self-defence when he shot and killed 17-year-old Trayvon Martin.

The case has sparked a fierce debate about race relations in the country.

Some of those demonstrating in New York described their reaction to the verdict and why they felt the need to take to the street.
