China blocks Tiananmen talk on crackdown anniversary

China's censors blocked internet access to the terms "six four", "23", "candle" and "never forget" on Monday, broadening extensive efforts to silence talk about the 23rd anniversary of China's bloody June 4 crackdown on pro-democracy protesters.

For China's ruling Communist Party, the 1989 demonstrations that clogged Tiananmen Square in Beijing and spread to other cities remains taboo, all the more so this year as the government prepares for a tricky leadership handover.
