Analysis of a telephone call established Abaaoud was in contact with Mehdi Nemmouche during January 2014. Nemmouche, a Franco-Algerian jihadist, shot and killed four people at the Jewish Museum in Brussels on 24 May 2014. Belgian authorities suspect him of having helped to organize and finance a terror cell in Verviers. This cell was raided on 15 January 2015 and two members of the cell were killed. In an interview with "Dabiq", the magazine of the Islamic State of Iraq and the Levant (ISIS), Abaaoud bragged on social media about going to Belgium to lead the cell but escaped back to Syria, even being stopped by a police officer who compared him to a photo but did not identify him. In July 2015, following the Verviers raid, he was convicted in absentia and sentenced to twenty years in prison by a Belgian judge for organizing terrorism.
