One of the brothers who carried out a massacre at the offices of the satirical French magazine Charlie Hebdo lived across the hall from the so-called "underwear bomber" while the two attended an Arabic-language school in Yemen in 2009, according to a published report.
The Wall Street Journal, citing neighbors of both men as well as Yemeni intelligence officials, reported that Said Kouachi and Umar Farouk Abdulmutallab studied together and often visited the mosque in the Old City of Yemen's capital, San'a.
This past Wednesday, Said Kouachi and his younger brother, Cherif, entered the Paris offices of the Charlie Hebdo magazine and killed twelve people, including eight of the magazine's staffers. Two days later, the brothers were killed by police who had surrounded them in a printing shop located in a small village about 25 miles northeast of Paris.
The Journal reports that Kouachi arrived in Yemen in early 2009 on a student visa issued by the language school and was often seen with Abdulmutallab
