HONG KONG (AP) — Several thousand people have marched through downtown Hong Kong in memory of the bloody crackdown on the Tiananmen Square protests in 1989.

The demonstrators marched from a large park to Hong Kong government headquarters on Sunday afternoon. A separate group continued on to the Chinese central government’s liaison office.

They renewed their long-standing demand for China’s Communist Party to overturn its official verdict that the protests that ended in bloodshed on the night of June 4, 1989, were a “counterrevolutionary riot.”

Twenty-five years later, Beijing still has not given an official account of the crackdown on the protests, which killed hundreds, if not more. The topic remains taboo in mainland China.

Broadcaster RTHK reported that police said up to 1,900 people took part in Sunday’s march, while organizers estimated 3,000.
