Reuters quoted Spanish police as saying in a statement, "Officers found three knives and ammunition in the home of the group leader, who had previously been arrested in Turkey in 2016 when he tried to enter a conflict area to join the (ISIS) terrorists and a fifth person suspected of being a member of the cell was serving."

Last month, the Spanish police evacuated the downtown area of Oviedo, northwest of the country, after a bomb was reported.
Western countries, especially European ones, are witnessing a state of security alert, fearing the return of terrorism, which some of those countries supported and condoned its crimes in Syria, to their territories, after terrorist attacks took place in European cities.
