Cherif Kouachi, 33

Said Kouachi, 34,

Two brothers were tonight named as being among the three suspects involved in a deadly terrorist attack on an anti-Islamist newspaper in France.

Said Kouachi, 34, and Cherif Kouachi, 32, were identified along with Hamyd Mourad, 18, with all three from the Paris commuter town of Gennevilliers.

At least 100,000 people gathered across France tonight to back the Charlie Hebdo publication, as a huge manhunt was launched to find the attackers.

The suspected Al Qaeda militants massacred 12 people in Paris today - and among those slaughtered was a police officer as he begged for mercy.

Tonight, thousands of people went to Republique Square near the scene to honour the victims, holding signs reading 'Je suis Charlie' - 'I am Charlie'.

The three suspects were tonight said by Metronews to be all French citizens - a homeless teenage man, and two brothers in their thirties.

There were disputed claims that the three men had been arrested 100 miles away in Reims, following a report by Libération. This could not be verified.

Cherif Kouachi was convicted in 2008 of terrorism charges for helping funnel fighters to Iraq's insurgency and sentenced to 18 months in prison.

Clad all in black with hoods and speaking French, the militants forced one of the cartoonists - at the office with her young daughter - to open the door.
