The Tiananmen Mothers group said on 2 June that they had received notice from the Beijing Municipal Public Security Bureau that they will not be permitted to travel to Beijing’s Wan’an Cemetery to mourn their loved ones or hold their customary commemorative activities on 4 June this year, the 37th anniversary of the atrocity. The group said it was the first time authorities had barred them from visiting their loved ones’ graves in more than 30 years. Banning the relatives of people killed in the Tiananmen crackdown from visiting their loved ones’ graves is a heartless act by the Chinese authorities. The Tiananmen Mothers were not previously blocked from cemetery visits on the 4 June anniversary, and it is deeply troubling that this year the suppression of Tiananmen commemoration appears to be escalating – reflecting the government’s deep-seated insecurity about people’s demands for accountability. The Tiananmen Mothers group is comprised of relatives of protesters killed during the 1989 crackdown. Every 4 June for more than three decades, the group has travelled to Wan’an Cemetery under police escort to mourn and to read memorial texts and eulogies in remembrance of their loved ones. The group has repeatedly called on the Chinese government to reveal the truth about the Tiananmen crackdown and demanded that those responsible are held accountable. Members have frequently been subjected to surveillance and other restrictions, particularly ahead of the 4 June anniversary date.
