PARIS/REIMS - Paris police issued arrest warrants for two brothers wanted for the attack on Charlie Hebdo weekly, saying they were "likely armed and dangerous", according to local media.

The hooded attackers stormed the Paris offices of Charlie Hebdo, a weekly known for lampooning Islam and other religions, in the most deadly militant attack on French soil in decades.

French police staged a huge manhunt for the attackers who escaped by car after shooting dead some of France's top cartoonists as well as two police officers. About 800 soldiers were brought in to shore up security across the capital.

Police issued a document to forces across the region saying the three men were being sought for murder in relation to the Charlie Hebdo attack. The document named them as Said Kouachi, born in 1980, Cherif Kouachi, born in 1982, and Hamyd Mourad, 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.

The Kouachi brothers were from the Paris region while Mourad was from the area of the northeastern city of Reims, the government source said.

The police source said one of the brothers had previously been tried on terrorism charges.
