The anti-extradition protests in Hong Kong on June 12 ended in chaos as police fired rubber bullets, tear gas and water cannons into the crowd, causing quite a number of injuries, some of them rather gory.

The Hong Kong police later reported that aside from a few rounds of rubber bullets and 20 beanbag shots, they also used up 150 canisters of tear gas, which is almost twice the number used against the Umbrella Movement demonstrators in 2014.

This video, created by a drone company, includes some fascinating aerial footage that gives you a sense of the size and scale of the protests, as well as the terror that was unleashed when the tear gas was fired.

Uploaded on June 15, the video has been seen more than 100,000 times and counting.
