Three people arrested in connectionwith the March 11 Madrid bombings were freed by a Spanish judge on Friday, court officials said.
After overnight consultations, Judge Juan del Olmo announced the release of two Syrian detainees Walid Altaraki and Mohamad Badr Ddin Akkad, and Moroccan Fouad Almorabit.
Altogether, 16 suspects are still in custody in connection withthe Madrid train blasts, which killed 202 and wounded more than 1,500.
Fourteen have been charged, and one of the other two was appearing before the court Friday.
The government said the investigation into the blasts is focused on the Moroccan Islamic Combatant Group, the forerunner ofSalafia Jihadia, which was accused of committing the Casablanca bombings that killed 45 people on May 16 last year.
Del Olmo has issued international arrest warrants for five Moroccans and a Tunisian, Sarhane Ben Abdelmajid Fakhet.
