A museum in Hong Kong commemorating the 1989 massacre in China’s Tiananmen Square has shut just three days after opening.
Hong Kong was the last place on Chinese soil where the ruling Communist Party's deadly attack on protesters in the Beijing square was commemorated with candlelight vigils and other events.
But authorities have banned public ceremonies for the second year amid a campaign by China to crush pro-democracy activism in the territory.
Organisers of the June 4 Museum said it closed on Wednesday after authorities investigated whether it had licenses to conduct public exhibitions.
The Hong Kong Alliance of Patriotic Democratic Movements of China said it wanted to protect staff and visitors while the group sought legal advice.
Public memorials to the incident have long been banned on the mainland. Relatives of people who were killed in the crackdown often are detained or harassed by authorities ahead of the anniversary.
The group, which has in previous years organised candlelight vigils in Hong Kong attended by thousands of people, said the museum received more than 550 visitors since it opened on Sunday.
Pro-democracy activists have been sentenced to prison under a national security law imposed following anti-government protests that began in 2019.
In past years, thousands of people gathered in Hong Kong’s Victoria Park to light candles and sing in memory of people killed when the military attacked protesters in and around Tiananmen Square, killing hundreds and possibly thousands of people.
Hong Kong authorities have banned the vigil for the second consecutive year, citing social distancing restrictions and public health risks from the coronavirus pandemic.
Critics say authorities use the pandemic as an excuse to silence pro-democracy voices in Hong Kong.
Last year, thousands gathered in Victoria Park despite the ban and police warnings.
Weeks later, more than 20 activists who took part in the vigil were arrested. This year, organisers have urged residents to mark June 4 by lighting a candle wherever they are.
