Hong Kong police drew their guns Sunday night after protesters attacked officers with sticks and rods, and brought out water cannon trucks for the first time, an escalation in the summerlong protests that have shaken the city’s government and residents. While a large crowd rallied in the park, a group of hard-line protesters took over a main street, strewing bamboo poles on the pavement and lining up orange and white traffic barriers and cones to obstruct police. After hoisting warning flags, police used tear gas to try to disperse the crowd.
