Twelve Murdered in Paris Attack
Police hunting the terrorists behind the massacre at the Charlie Hebdo satirical newspaper have made "several arrests", French Prime Minister Manuel Valls said.
Photographs of two prime suspects in the Paris attack have been released by police - as a third man handed himself in.
Hamyd Mourad, 18, surrendered to police after hearing his name on the news in connection with the attack, a judicial official said.
But a massive manhunt for the other two suspects, brothers Said Kouachi and Cherif Kouachi, continues with thousands of police scouring the streets of France for them.
Mr Valls said preventing another attack "is our main concern," as he explained why authorities released photos of the two men along with a plea for witnesses to come forward.
Twelve people died in the attack on the offices of Charlie Hebdo, a weekly newspaper that had been threatened before for its caricatures of the Prophet Muhammed.
Eight journalists, two police officers, a maintenance worker and a visitor were killed, said prosecutor Francois Molins.
Another 11 people were wounded, four seriously.
The terror attack has been condemned by global leaders and France's president Francois Hollande has declared a national day of mourning today following the bloody raid - France's worst terror attack since 1961.
David Cameron described the attack as "sickening" while Deputy Prime Minister Nick Clegg said the killings were a "barbaric attack on freedom of speech".
The Queen, meanwhile, sent "sincere condolences" to the victims' relatives.
Home Secretary Theresa May will chair a meeting of the Government's emergency committee Cobra today.
