The Guardian is reporting that three suspects in this morning's deadly attack at the Charlie Hebdo office in Paris have been arrested, though that report is unconfirmed. The suspects have reportedly been identified as Said Kouachi and Cherif Kouachi, two brothers in their early 30s, and 18-year-old Hamyd Mourad.

UPDATE 4:55 pm: Not long after the Guardian published their report, it was edited and a second paragraph was added. It now reads:

A spokesman for the French police tells the Guardian's Kim Willsher in Paris that authorities have arrested three suspects in the Charlie Hebdo attack.

However Kim points out that the interior minister, Bernard Cazeneuve, addressed the media not long ago and did not mention arrests.

Earlier in the evening, Le Monde and Metro News reported that police had identified three suspects, though no names or descriptions were released.

UPDATE 5:05 pm: Sky News is reporting that two of the suspects are brothers.

From Sky News:

The men have been named as French nationals Said Kouachi and Cherif Kouachi, in their early 30s, along with 18-year-old Hamyd Mourad. His nationality is unknown.

French police officials have said the suspects are linked to a Yemeni terror network.

Cherif Kouachi was reportedly convicted in 2008 of terrorism charges for helping channel fighters to Iraq's insurgency. He was jailed for 18 months.

UPDATE 6:04 pm: French anti-terror police have launched a raid in the northeastern city of Reims, where the suspects are rumored to be hiding.

UPDATE 6:52 pm: One of the suspects was reportedly killed during the raid. The other two are in custody, according to NBC News.
