Tens of thousands of people have gathered in Hong Kong to mark the 30th anniversary of the crackdown on protests in Beijing's Tiananmen Square.

Axar.az reports citing BBC.

Hong Kong and Macau are the only places in China where people can commemorate the activists killed in 1989.

China has never given an official figure for how many people died, but estimates begin in the hundreds.

Organisers say 180,000 people took part in a vigil, centred in the city's Victoria Park.

But police put the number of attendees at less than 40,000.

Elsewhere in China, the authorities have banned even oblique references to the crackdown, which took place after weeks of mass protests that were tolerated by the government. The numbers gathered in and around the square are estimated to have reached a peak of one million people.

Hundreds of security personnel and police were monitoring the square in Beijing on Tuesday.
