Paris terror attacks: Thousands attend vigil in Trafalgar Square

Thousands gathered in Trafalgar Square as vigils for the Paris attacks took place around the world.

Many brought flags and signs reading: 'Paris, je t'aime', 'London stands with Paris', 'Give peace a chance'.

Occasionally they broke into songs — the Marseillaise, Champs Elysee — and spontaneous applause.

The mood was described as quieter than a similar event following the Charlie Hebdo shootings a year ago.

The vigil was well attended despite the rain, which could be seen streaming through the light projecting a Tricolour onto the National Gallery.

Union flags will also be flown at half-mast across London, including from the Guildhall, The Mansion House and Old Bailey.
