The United States of America was rocked last year by protests followed by riots, triggered by the killing of an unarmed black teenager Micheal Brown by Darren Wilson, a white police officer.

Things worsened after the policeman was let off by the court. The turmoil that gripped the US just a year ago, seems to have returned to Ferguson on Brown's death anniversary.

A state of emergency has been declared in Ferguson after protests on Sunday turned violent towards the evening. A day of protests took an ugly turn when shots were fired while police tried to disperse the protesters shouting anti-police slogans.

An 18 year old black individual was critically injured. The governor of Misissipi condemned the violence as unfortunate and appealed for peaceful protests the following day.
