According to the local newspaper El Mundo, four of the detainees are also suspected of links to the terrorist attack in Brussels in 2016. At that time, 35 people were killed and 340 others were injured.
Note that as a result of the operation, the police seized three pistols. In this case, the special operation was initiated by the national court of Barcelona.
Thus, the investigation against the detainees began about eight months ago on the basis of data provided by the police of Belgium.
Recall, as previously reported, "URA-Inform," the responsibility for a number of terrorist attacks in Brussels took over the terrorist organization "Islamic State".
