Hong Kong police on Sunday detained several key pro-democracy figures attempting to commemorate the anniversary of the bloody Tiananmen crackdown, as hundreds in democratic Taiwan mourned the dead in a candlelight vigil.
For years, tens of thousands of Hong Kongers would converge on the city's Victoria Park and its surrounding Causeway Bay neighbourhood to commemorate the events of June 4, 1989 -- taking part in candlelight vigils.
But since Beijing's imposition of the national security law on Hong Kong in 2020 to quell dissent, the annual vigil was banned, and the organisers charged under the law.
This weekend, scores of police were deployed in the area, stopping people to search their belongings and question them. An armoured vehicle was sighted parked near a shopping centre.
Anyone found with a candle -- regarded as a symbol of the Victoria Park vigil -- was questioned and even detained, while police appeared to cast a broad net on what was deemed offensive.
More than 700 kilometres (430 miles) away, nearly 500 people gathered at Taipei's Liberty Square to chant "fight for freedom, stand with Hong Kong" as night fell.
They lit candles in the shape of "8964" -- numerals forbidden in mainland China because it references the events of June 4, 1989.
"We need to cherish the freedom and democracy we have in Taiwan," Perry Wu, 31, told AFP. "I feel really sad to see the news of people getting arrested today in Hong Kong."
By evening, AFP reporters in Hong Kong had witnessed more than a dozen people taken away by police in vans.
Among the most prominent was Chan Po-ying, the leader of the city's League of Social Democrats, one of the last few remaining opposition groups.
The veteran activist was holding a small LED candle and two flowers, before she was seized by police.
Other recognisable figures detained were Alexandra Wong, a well-known activist nicknamed "Grandma Wong", former chairwoman of the Hong Kong Journalists Association Mak Yin-ting, and Leo Tang, a former leader of the now-disbanded Confederation of Trade Unions.
At Victoria Park, a man sitting on a bench holding an unlit candle was surrounded by cops. As he was led to a police van, he said, "I raised a candle... I was (taken) for just sitting there."
The swift removal of people comes a day after police arrested four for "seditious" acts and "disorderly conduct". Another four people were detained on suspicion of breaching the peace.
- 'Let the world know' -
Discussion of the Tiananmen crackdown is highly sensitive for China's communist leadership and commemoration is forbidden on the mainland.
The government sent troops and tanks to Beijing's Tiananmen Square in 1989 to break up peaceful protests, brutally crushing a weeks-long wave of demonstrations calling for political change.
Hundreds -- by some estimates, more than 1,000 -- were killed.
For decades, Hong Kong was the only Chinese city with a large-scale commemoration -- a key index of the liberties and political pluralism afforded by its semi-autonomous status.
But after the vigil was banned since 2020, the park was barricaded with metal barriers.
This year, Victoria Park was transformed for a "hometown carnival fair" organised by pro-Beijing groups.
"The pro-Beijing camp want to... occupy the venue to exclude the mourners," said Chiu, a 68-year-old retiree, who sat on a park bench with an unlit candle by him in quiet defiance -- a short distance from the fair.
- Erase memories -
Beijing has gone to exhaustive lengths to erase the 1989 event from public memory in the mainland.
All mention of the crackdown is scrubbed from China's internet.
Over the weekend, sites of more recent protests -- a bridge in Beijing where a "freedom" banner was unfurled, and Wulumuqi Street in Shanghai where demonstrations happened in November -- also saw heightened security.
Hong Kong authorities were vigilant in the weeks before June 4, with police seizing a commemorative "Pillar of Shame" statue for a security trial and removing books on the Tiananmen crackdown from public libraries.
But there were still pockets of defiance Sunday around Hong Kong -- a shop gave away candles, while a bookstore displayed Tiananmen Square archival material.
- 'Freedom to mourn' -
Sidestepping questions about whether public mourning was allowed, Hong Kong's leader John Lee had repeatedly maintained that the public must act according to the law or "be ready to face the consequences".
Vigils planned around the world, from Japan to Sydney, saw people stand solemnly with a candle next to images of the 1989 crackdown.
Hong Kong activist Wong Yat-chin, currently in prison for a national security charge, said he mourned the "loss of the freedom to mourn".
"It's not a crime to remember a day," he said on his Instagram page Sunday.
