Alwaght-At least 12 people have been killed after gunmen opened fire in the headquarters of the satirical newspaper Charlie Hebdo in central Paris. The hooded attackers with possible links to al-Qaida stormed the weekly known for lampooning Islam and other religions, in the most deadly militant attack on French soil in decades .
French police were still in a huge manhunt for two of the attackers who escaped by car after shooting dead some of France's top cartoonists as well as two police officers .
Police issued a document to forces across the region saying the men were being sought for murder in relation to the Charlie Hebdo attack .
The document, reviewed by a Reuters correspondent, named them as Said Kouachi, born in 1980, Cherif Kouachi, born in 1982, both from Paris, and Mourad Hamyd, born in 1996 .
The police source said one of them had been identified by his identity card, which had been left in the getaway car .
An official at the Paris prosecutor's office said the youngest of the three had turned himself in at a police station in Charleville-Mézières, some 230 kilometers northeast of Paris near the Belgium border .
BFM TV, citing unidentified sources, said the man had decided to go to the police after seeing his name in social media. It said other arrests had taken place in circles linked to the two brothers .
The police source said Cherif Kouachi had previously been tried on terrorism charges and served 18 months in prison .
He was charged with criminal association related to a terrorist enterprise in 2005. He had been part of an Islamist cell that enlisted French nationals from a mosque in eastern Paris to go to Iraq to fight Americans in Iraq. He was arrested before leaving for Iraq to join militants .
Police published pictures of the two brothers Thursday morning calling for witnesses and describing the two men as "armed and dangerous ."
The police source said anti-terrorism police searching for the suspects and links to them had carried out searches in Reims, Strasbourg and Paris as part of the investigation .
