Spanish police believe they have identified six Moroccans who carried out the train blasts which killed 200 people in Madrid last week, newspaper El Pais said on Tuesday, citing security sources.
One of those identified, who has already been arrested, was recognized by two survivors of the blast who said they saw him before the explosions took place.
El Pais said the suspect, Jamal Zougam, had connections with some of those arrested for last May’s bombings in Casablanca which killed 45 people, including 12 suicide bombers.
Interior Ministry officials could not be immediately reached for comment.
Police sources told El Pais they believed the six Moroccans may have formed only part of the group which carried out Thursday’s attacks and they suspected militants from other nationalities were involved.
Moroccan officials have challenged theories of any direct link between the Madrid bombers and radical Islamists who staged the Casablanca attack.
