Spanish police have reportedly arrested 15 people suspected of recruting Islamic militants to fight in Iraq and Afghanistan.
It is understood the detainees include 13 Moroccans and two Algerians.
It follows raids early this morning in several towns and cities in the north-eastern region of Catalonia, including Barcelona.
Some of those detained were captured in Aranjuez, south of Madrid, while another was arrested in the resort city of Malaga.
Documents, diaries, computers, mobile telephones and papers related to jihad were seized, in an operation that police said was connected to the arrest of 22 jihadists in January.
Spanish police have now arrested over 100 Islamist suspects since deadly train bombings in Madrid in 2004, detaining some over an alleged plot to blow up Madrid’s High Court.
