Michael Brown shooting: New York protesters march

There has been a violent response to the decision by a grand jury in the US state of Missouri not to bring charges against the police officer who shot dead an unarmed black teenager, Michael Brown.

In the St Louis suburb of Ferguson, shops were looted and cars and buildings set ablaze as police and demonstrators clashed.

In New York, hundreds of protesters marched to show their anger ahead of the decision.

The BBC's Anna Bressanin spoke to some of them as they headed from Union Square towards Harlem.
