The United States has urged China to make a full public account of those killed, detained or who went missing during a crackdown on student-led pro-democracy protests in and around Beijing's Tiananmen Square in 1989, Secretary of State Mike Pompeo said.
The Chinese government sent tanks to quell the June 4, 1989, protests, and has never released a death toll. Estimates from human rights groups and witnesses range from several hundred to several thousand.
The Tiananmen crackdown is a taboo subject in China and 29 years later it remains a point of contention between China and many Western countries.
