Ibrahim El Bakraoui, one of the suicide bombers in the attacks at  Brussels airport, was on a US counterterrorism watch list even before the November Paris attacks, CNN reported Friday, citing a US official.

His brother Khalid, who blew himself up at Brussels' Maalbeek metro station, was added to the list "soon after the Paris attacks," CNN said. Ibrahim was deported by Turkey to the Netherlands in July, after being arrested in June by Turkish authorities near the Syria border.
