Cherif Kouachi, who carried out the attack along with his brother, travelled to Yemen in 2011 and might’ve met with Anwar al-Awlaki, two counter-terrorism officials told the news agency. The officials have also pointed out that while AQAP has already claimed responsibility for the attack, so far no evidence of communication between the terrorist organization and the Kouachi brothers in recent months has been uncovered.
CNN also points out that while AQAP didn’t claim responsibility for the siege that occurred in a kosher grocery store in Paris that occurred following the Charlie Hebdo attack.
CBS News points out, however, that Ahmedy Coulibaly, an ISIS follower responsible for the kosher supermarket hostage crisis, claimed that he was operating in concert with the Kouachi brothers. "Some of this was done together and some of it alone, in order to have a greater impact," he said on tape prior to the attack, according to the news agency.
