Thousands of Hong Kong protesters defy police ban to march for 13th week of protests

Police fired tear gas Saturday morning in Hong Kong to break up what is the 13th weekend of pro-democracy demonstrations. Protesters were also hit with blue-dyed water when police used a water cannon to try to push them away from the barricaded zone. Authorities say some protesters responded and threw gasoline bombs towards police lines. The violent clash is happening near the Chinese government's main office in the city. Ramy Inocencio reports.
