A Spanish newspaper revealed that Qatar financed centers of Islamic worship and mosques in Spain, particularly in the province of Catalonia, where the terrorist attacks happened.

The newspaper said in its report that Doha supports the places of worship there through wealthy businessmen, which lead to the growth of the phenomenon of extremism in Spain.

The Barcelona attack, which was adopted by ISIS organization, recalls to mind earlier discussions related to the funding of mosques frequented by extremists in Europe and its relation to terrorist attacks that claimed innocent lives.

A report published in the Spanish newspaper "La Razón" exposed the funds coming from abroad, especially from Doha to centers of worship in Spain in Catalonia, which became, according to the newspaper, a stronghold of extremism and terrorism.

The report said that islamic centers and mosques have been under Spanish security control for years since it started receiving funding from Qatar through wealthy businessmen.

The data indicate that seven percent of Muslims in Spain, estimated at two and a half million people are based in Catalonia.

Spain has more than 1,260 Islamic worship centers, of which 256 are in Catalonia alone, where the highest numbers of immigrants live.
