Spanish police yesterday arrested four people suspected of using social media to brainwash and recruit people to violent groups like the Islamic State, the interior ministry said. Two of those were arrested in the Spanish North African enclave Melilla and ran web pages promoting the cause of various groups, especially IS, translating material into Spanish, the ministry said in a statement. “Both those arrested, who shared the strategy of the terrorist group Daesh (the Islamic State), recruited women who, after a process of indoctrination, ended up joining the terrorist group,” it said.
