After the chaos at the airport last night, some protesters are saying they're sorry.
On Telegram -- an encrypted messaging app popular with protesters -- some are sharing images apologizing for last night. But it's unclear how widespread these feelings are within the movement, because only a small handful of people have posted these sentiments.
One person, who posted anonymously in a Telegram group with more than 34,000 members, explained that people had become more aggressive after police posed undercover as protesters.
"This has led to our unsuppressed anger and overly aggressive way to respond," the person wrote.
Another post on the app was of a picture featuring a yellow hard hat -- something protesters often wear to demonstrations as a safety measure -- alongside this message:
Joshua Wong, who was a leader of the 2014 Umbrella Movement, also tweeted an apology, saying that: "Hong Kong is sick."
"We thank you for your tolerance and understanding," he said.
The Telegram channel's admin group is anonymous, and no group or spokesperson released these messages. The protest movement does not have a centralized leadership that conveys messaging.
In addition to the apologies, a handful of other posts appear to show protesters urging their fellow demonstrators not to apologize.
"Whoever apologized means they are breaking off their relationship with front-line protesters," wrote one user of LIGHK, an online forum that is considered Hong Kong's answer to Reddit.
