Eight men have been arrested in Barcelona, accused of having links to radical Islamic cells in Pakistan and collaborating with the group that carried out the attacks in Mumbai in 2008, media reported on Wednesday.
Seven Pakistani men were arrested on Tuesday and one north African man was arrested on Wednesday morning, media said.
The men belonged to a group that made fake identification documents which were sent to Pakistan to be used in attacks, the media reported.
They were also accused of sending money and fake documents to the militant group Lashkar-e-Taiba, which was blamed for the attacks in India in November 2008 in which 166 people were killed.
No one was immediately available at the Interior Ministry to confirm the reports. The ministry provided no other details, but Spain's leading Cadena SER radio says the detainees formed part of a group based in Thailand and linked to Lashkar-e-Taiba, a Pakistan-based terror group blamed for the 2008 Mumbai attacks that killed 166 people.
The arrests took place late on Tuesday and early Wednesday in the northeastern city of Barcelona and in the surrounding region of Catalonia.
SER and other Spanish media say the arrested are mostly Pakistanis who robbed passports that were later doctored and sent to Thailand for distribution to groups linked to al-Qaida. (With AP inputs)
