In February 2010 , a Yemeni security official said that 43 people were being interrogated for links to the Christmas Day attempt , including foreigners , some of them studying Arabic and others married to Yemeni women . Abdulmutallab was thought to have used Arabic studies as a pretext for entering the country . Said Kouachi , one of the attackers – now deceased – in the Charlie Hebdo shooting , is believed to have been one of Abdulmuttalab 's roommates at the Yemeni Arabic language school
