The National Union of Journalists has called on all supporters of press freedom to join in a minute's silence from 11am today.
NUJ general secretary Michelle Stanistreet said: "Following yesterday’s shocking and sickening assassinations of journalists at satirical magazine Charlie Hebdo and attending police officers, the NUJ is calling on all members to observe the minute’s silence called by colleagues in France this morning at 11am our time (noon in France).
"The NUJ, together with journalists and their unions around the world, has condemned this attack as an attempt to gag press freedom and attack the entire profession. Please join us all in stopping work for one minute to pay our collective respects to colleagues who have paid the ultimate price in carrying out their work."
Meanwhile, UK police officers are set to pause today at 10.30am "in solidarity and sympathy" for the French officers murdered yesterday in the Charlie Hebdo massacre.
