MADRID, Spain (CNN) -- Spanish authorities believe they have identified at least six Moroccans who carried bombs onto Spanish commuter trains last Thursday, killing 201 people.
Only one of the men, named as 30-year-old Jamal Zougam, is in custody.
Zougam has been linked to two men charged over the suicide attacks in Casablanca that killed nearly three dozen people in 2003, authorities say.
That bombing has been tied to al Qaeda.
Zougam is also believed to be a follower of Imad Eddin Barakat Yarkas, the alleged ringleader of al Qaeda in Spain, according to a Spanish court document.
The Spanish government initially zeroed in on Basque separatist group ETA -- listed as a terrorist organization by the United States and European Union -- as the prime suspect. Since then, authorities have placed six people in custody, all non-ETA members.
Meanwhile, Basque police in northern Spain have detained an Algerian man, Ali Amrous, a local government official said Tuesday.
Police said Amrous was involved in a disturbance in January in San Sebastian, telling police: "There are going to be some deaths on the Castellana, on the Plaza Castilla and in Atocha."
The Castellana is a major north-south thoroughfare in Madrid, the Plaza Castilla is a major intersection on that route and Atocha is the name of the station hardest hit in the bombings.
Police remembered Amrous' statement and tracked him down.
In addition to Zougam and Amrous, authorities have detained two other Moroccans and two Indians.
While the country continues to mourn, thousands of Spaniards attended a special mass Tuesday evening in Madrid's Almundena cathedral to remember the bombing victims.
Queen Sophia and international diplomats joined the mourners, as the city's archbishop said the attacks plunged everyone into deep pain.
In the wake of the bombings, Spanish Interior Minister Angel Acebes announced Monday that a European Union anti-terrorist conference would be held Friday in Madrid.(Full story)
The U.S. intelligence community is considering the possibility that the bombings may have been carried out by a number of people with various ties to terrorist groups, the senior administration official said, adding that theories include the following possibilities:
Islamic fundamentalists with support from ETA.Islamic fundamentalists with close ties to al Qaeda, although not necessarily "card-carrying members of al Qaeda."Members of ETA or al Qaeda.CNN Investigative Producer Henry Schuster and Pentagon Correspondent Barbara Starr contributed to this report.
