Trafalgar Square rally for Paris: 'We're all united here'
A crowd has gathered in Trafalgar Square in London as part of a unity rally to remember the victims of the attacks in France.
People held up pens and pencils as a sign of unity with Charlie Hebdo the French satirical magazine which was attacked on Wednesday.
The rally was timed to co-ordinate with a huge march in Paris, where more than a million are thought to have attended alongside with world leaders.
French and British people living in London told the BBC why they were taking part in the rally.
