Al Qaeda in the Arabian Peninsula has come forward claiming responsibility for the attack on the Charlie Hebdo offices that left 12 dead. In a video originally uploaded to YouTube, Yemeni al Qaeda leader Nasser bin Ali al-Ansi heralds brothers Cherif and Said Kouachi as "two heroes of Islam."

Amedy Coulibaly, who took fourteen hostages and killed four in a kosher supermarket before he was shot and killed by French special forces on Friday, pledges allegiance to the Islamic State in a video released today on what is reportedly an official ISIS forum.

A French official has confirmed to the Associated Press that Cherif and Said Kouachi have holed up inside a printing house in Dammartin-en-Goële, northeast of Paris, and have reportedly taken at least one person hostage. Police and the gunmen, accused of killing 12 people in Wednesday's Charlie Hebdo office massacre, traded fire Friday as helicopters descended on the scene.

The two main suspects in Wednesday's Charlie Hebdo killings, Said and Chérif Kouachi, were reportedly spotted Thursday robbing a gas station about 50 miles northeast of Paris.
