Trafalgar Square crowds pay tribute to Paris terror victims

Landmarks across London have lit up in the colours of the French flag in a tribute to the victims of last week's terror attacks.

Downing Street said the Union flag at Number 10 was lowered to half-mast at the start of the rally "as a mark of solidarity and respect".

Hundreds of people are at a rally in Trafalgar Square in honour of the victims of last week's terror attacks in Paris.

Deputy Prime Minister Nick Clegg has joined the crowds and London Mayor Boris Johnson is expected to attend soon.

Crowds of people, many holding banners reading 'Je Suis Charlie,' gathered in Trafalgar Square this afternoon in support of the victims of last week's terror attacks in Paris.

London landmarks, including Trafalgar Square, will be lit up in the colours of the French flag later today, in a show of unity with the citizens of Paris.

As it was announced that London landmarks would be lit up today in tribute to the Paris terror attack victims, Boris Johnson said it was important that Londoners demonstrate "solidarity" with the French capital.

London's landmarks will display the French colours this evening in a special tribute to pay respect to the victims of the Paris massacre.

Vigils have already been held in London and all over the world following the death of 17 people after the attack on the Charlie Hebdo offices and the subsequent manhunt of Said and Cherif Kouachi, as well as conspirator Amedy Coulibaly.

Tower Bridge will display the flag's colours from 4pm until 5.30pm, after which the bridge will go dark, while the emblem will also be projected on to the National Gallery.

The Trafalgar Square fountains will rotate the colours of the French national flag, while the London Eye will go dark with the red, white and blue projected on to County Hall behind it.
