Spain's National Police have detained two Syrian nationals suspected of having ties with terrorist groups responsible for promoting extremism, the Interior Ministry announced in a press release.
"The detainees showed a high level of radicalization and acted as important informative promoters, spreading the doctrine of the jihadist groups Daesh* and Al Qaeda*," the document reads.
The police stated that both men were members of special groups in messaging services which had been used to spread propaganda. One of the detainees was a high-ranking operative within Daesh's information dissemination network.
The terrorism alert level in Spain remains high, which means that the government qualifies the possibility of terror attacks in the country as "highly likely." In August 2017, the Spanish cities of Barcelona and Cambrils suffered two terrorist attacks, for which the IS claimed responsibility.
*Daesh (also known as ISIS/ISIL/Islamic State) and al-Qaeda are terrorist groups banned in Russia and several other countries.
