Hong Kong police apologised for firing a tear gas canister into a pharmacy in Kowloon during an operation to clear the streets of anti-government protesters. A police tear gas canister also hit the wall panel of a nearby noodle shop, setting it on fire. As Hong Kong's political crisis enters its 21st week, residents living between Yau Ma Tei and Mong Kok - a major flashpoint in the protests - have become more divided in their views of the unrest.
