Curfew fails to quell US violence

Police arrested seven protesters in Ferguson, Missouri, early yesterday as they imposed a curfew aimed at quelling days of violence that erupted after an unarmed black teenager was shot dead by a white police officer

The latest confrontation occurred when demonstrators remained in the streets of the St Louis suburb after the curfew took effect at midnight. Seven people were arrested for failing to disperse, police said.

A person was shot and critically wounded during the night. It was not clear why, and the shooter was still at large, police said.
