Police fire tear gas to disperse protesters in Missouri

Police fired smoke cannisters at demonstrators remaining in the street past curfew in Ferguson, Missouri, early on Sunday, in the latest clash over the shooting of a black teenager by a white police officer.

Police, who were equipped in riot gear and had armored cars, used a bullhorn to warn demonstrators to clear the streets. The number of protesters remaining in the street past curfew had been about 150 people, police said.
