LONDON’S Trafalgar Square was flooded with thousands of people this weekend to unite in solidarity with the victims of the Paris massacre.

The French flag, the Tricolore, was projected onto the National Gallery as the crowds sang the Marseillaise, during a vigil that was described as “at once sombre, defiant and boisterous.”

Candles and phones were held by attendees in the darkness, as the square’s fountains lit up in blue, white and red.
