# Authorities in Beijing and Hong Kong have implemented heightened security measures as China marks the 37th anniversary of the Tiananmen Square crackdown. The protests were initially sparked by the death of a pro-reform leader, but students expanded their demands to include freedom of speech and media, democratic reforms, and an end to government corruption. State media reported the known death toll at the time as about 300, mostly soldiers, with only 23 students confirmed killed, but rights groups and witnesses say the figure could run into the thousands.
