Instagram did not respond to a request for confirmation.
Many of the images have been posted with the hashtag "#OccupyCentral" or "#OccupyHK." The phrase "Occupy Central" was blocked on Sunday on Weibo, a Chinese microblogging site similar to Twitter, reported Reuters.
Blocking Instagram in China does not prevent people in Hong Kong from posting images of the protests or prevent people in other countries from viewing the images. The protests started as sit-ins over a week earlier by students calling for Beijing to grant genuine democratic reforms to the semi-autonomous city.
