Anti-government protesters set up barricades and light fires in standoffs with officers. Riot police have charged at hundreds of protesters in a busy downtown district in Hong Kong after some demonstrators had started a fire outside a police station. Earlier in the day, protests broke out in several areas of Hong Kong as security measures tightened at the airport in an attempt to stop protesters’ plans to paralyse the travel hub. The confrontations came as anti-government demonstrations, aimed at drawing global attention to the semi-autonomous Chinese city’s political crisis, came to the end of their 13th week. On Saturday night, the crowds chanted anti-police slogans and sang provocative songs outside the Mong Kok police station and shone laser beams at riot officers. They built make-shift barricades with roadside barriers and other objects, and as police threatened to fire rubber bullets and sponge rounds, some started a fire. “Reclaim Hong Kong! Revolution of the era!” many chanted. The fire was put out minutes later by the fire brigade. Riot police then began to charge at protesters, chasing them into surrounding streets. But many remained in the area and led the police in a game of cat and mouse. The police presence in the area remained heavy as of late Saturday. Some passers by verbally attacked protesters for causing disruptions. It followed a night of violence in which riot police fired teargas and sponge rounds in the Mong Kok district to disperse crowds. Mong Kok has become a hot spot for protests during the past week as emotions ran high after violent clashes took place last Saturday inside the Prince Edward station, in which police rushed into the station and brutally beat a number of protesters inside a train carriage. The police attack fuelled rumours of deaths and a large number of flowers have been left outside the entrance of the metro station. A small group tried to submit a petition to urge the MTR metro company to release CCTV footage of the police on Saturday afternoon at the station, shortly before staff announced its closure. A similar protest took place outside the Mong Kok police station late on Friday, prompting riot police to fire teargas and bean bag rounds as some had built barricades on streets and set fire to them. Hong Kong’s government said on Saturday that reports of people dying as a result of the police action were “false” and “malicious” rumours. Saturday’s demonstrations across Hong Kong were mostly aimed at voicing anger over the police’s use of force, which has escalated as tension reached boiling point during the past three months. Many protesters have insisted the Hong Kong government meet their political demands, including setting up an independent body to investigate the police’s alleged excessive use of force since the protests started in June. Earlier in the week, Hong Kong’s leader, Carrie Lam, withdrew a controversial extradition bill, which originally ignited the protests. But protesters remain angry about alleged police brutality and have vowed to continue demonstrations. In a front-page editorial on Saturday, the overseas edition of the Communist party’s mouthpiece People’s Daily’s said “a small bunch of extremely violent elements have become the vanguards of foreign and anti-China forces” and were trying to “disrupt Hong Kong and paralyse the government to make it into an independent or semi-independent political entity”. At the airport, riot police carrying helmets and shields patrolled areas in and around the venue and guarded its main entrances. Airport staff only admitted travellers with passports and boarding passes after a court injunction was issued earlier. A water cannon truck was spotted near the airport. Dozens of riot police also stopped airport-bound buses throughout the day, carrying out detailed searches of passengers’ luggage and checking their ID. They removed people they suspected of being protesters, some of whom were carrying gas masks and other protective gear. The airport express railway linking the airport to the city closed several stations, only operating services from the Hong Kong station terminus, where dozens of riot police were standing guard. Several bus services also suspended services to the airport, diverting to a neighbouring residential district, Tung Chung, and the airport ca park was closed. Last Sunday, thousands of demonstrators paralysed traffic and shut down transport links between the city and the airport. Travellers were stranded as train and bus services were suspended and roads were heavily congested. Flights were cancelled and delayed.
