Earlier, a government official erroneously said one warrant was for Abdelkrim Mejjati, a 36-year-old Moroccan who was convicted in absentia in the deadly bombings in Casablanca last year, which killed 33 people and 12 suicide bombers. Mejjati is wanted by the FBI in connection with possible terrorist threats against the United States.
Spanish police have 19 people in custody -- 11 Moroccans or Moroccan-born Spaniards, two Indians, two Spaniards, and three Syrians. The nationality of one suspect, whose arrest was announced yesterday, was not released.
Fourteen of the suspects have been charged with mass murder, or collaborating with or belonging to a terrorist group.
Interior Minister Angel Acebes on Tuesday identified the Moroccan Islamic Combatant Group as the main focus of investigation in the March 11 bombings in Madrid, which killed 191 people and injured more than 1,800 others. That extremist group is a forerunner of Salafia Jihadia, which Morocco blamed for the Casablanca bombings.
At least five members of the Combatant group, including alleged leaders Nouredine Nfia and Salahedine Benyaich, trained in Al Qaeda camps in Afghanistan between 1999 and 2001, Moroccan officials said.
Spanish investigators have analyzed a videotape in which a man claiming to speak on behalf of Al Qaeda said the group carried out the Madrid attacks in reprisal for Spain's support of the US-led war in Iraq.
In the investigation, Moroccan Mustapha Ahmidam and Antonio Toro Castro, the brother-in-law of a Spaniard charged with supplying dynamite to the bombers, were questioned by the judge yesterday.
Ahmidam was released, and Castro was ordered to return to court tomorrow.
Another Moroccan, Fouad Almorabit, was arrested again yesterday.
