Several hundreds of protesters, many of them young and donning black T-shirts, handed out anti-government flyers in more than 16 languages to arrival passengers at the Hong Kong International Airport on Friday.

"Please forgive us for the 'unexpected' Hong Kong," the English leaflets read. "You've arrived in a broken, torn-apart city, not the one you have once pictured. Yet for this Hong Kong, we fight," the flyers said according to Reuters.

Protesters said they wanted to reiterate their demands and put their case "in front of an international audience," according to social media posts from demonstrators.

The massive travel hub connects the city to more than 220 global destinations and served 74.7 million passengers last year, according to the airport's website.

Airport authorities said only departing passengers with travel documents will be allowed to enter Terminal 1 on Friday morning, as the airport braces for what protesters are describing as a three-day event. The terminal serves long-haul flights.

Online platforms such as Instagram, Telegram, Airdrop and local Hong Kong forums have become the main means of organization among protesters because they give some anonymity to users.

The demands were originally released in July, a day after a small group of protesters stormed the Hong Kong legislature:

a full withdrawal of a proposed bill that would allow Hong Kong people to be extradited to mainland China

a retraction of any characterization of the movement as a "riot"

a retraction of charges against anti-extradition protesters

an independent committee to investigate the Hong Kong police's use of force

universal suffrage in elections for the city's chief executive officer and legislature by 2020

So far, Hong Kong authorities have given no concessions, though Chief Executive Carrie Lam "suspended" the extradition bill last month.
