China increases pressure to erase Tiananmen protest memory on 37th anniv.

BEIJING - China tightened security and stepped up efforts on Thursday to erase the memory of the 1989 military crackdown on pro-democracy protesters in Beijing's Tiananmen Square, with victims' families barred from visiting a cemetery on the 37th anniversary.

All forms of public remembrance were banned in mainland China, with large numbers of police officers and vehicles deployed near the square in the run-up to the anniversary to prevent any attempts to honor the victims. The incident left at least hundreds dead.
