China calls Rubio remarks about Tiananmen Square an "attack"

Beijing hit back Wednesday at Secretary of State Marco Rubio for saying the world will "never forget" the deadly Tiananmen Square crackdown in 1989, describing his remarks as an "attack" on China.

Chinese troops and tanks forcibly cleared peaceful protesters from the square in the capital on June 4, 1989 after weeks-long demonstrations demanding greater political freedoms.

The exact toll is unknown but hundreds died, with some estimates exceeding 1,000 people.
