US police made numerous arrests during a tense night-time standoff in Ferguson on August 10, after St. Louis County declared a state of emergency and a teenager was charged with shooting at police officers. Protests came after unrest and a shootout in Ferguson on August 9 night that led county officials to declare a state of emergency on August 10. AFP PHOTO / MICHAEL B. THOMAS
