Spanish police have arrested 11 people suspected of setting up a support network for an Islamic extremist group linked to al-Qaida.

Interior Minister Jose Antonio Alonso told reporters Wednesday the suspects belong to a cell linked to the Algerian-based Salafist Group for Preaching and Combat. The group is part of the al-Qaida terror network.

Officials say the 11 were captured in and around the Spanish provinces of Alicante and Murcia, and the city of Granada. They are suspected of involvement in drug trafficking and credit card fraud.

The arrests followed an investigation into ties between the cell and other groups in Germany, Belgium, Britain, and Denmark.

Spain has arrested more than 150 terror suspects over the last two years, mostly in connection with last year's Madrid train bombings.
