Black badges reading "Je suis Charlie" are being posted online after at least 10 journalists and two police officers were shot dead in a brutal gun attack on the French satirical magazine Charlie Hebdo.
Shots were fired at the headquarters of the satirical magazine in central Paris and the gunmen are believed to still be at large.
Supporters posted the mournful black slogans, which translate as "I am Charlie" using the magazine's distinctive font, to condemn the killings.

Charlie Hebdo replaced its own website with a single image of the phrase.
No-one has yet claimed responsibility for the attack.
The publication is well-known for its controversial cartoons particularly
those depicting Islamic figures and just about every one else.
