Madrid ( CNN ) Spanish authorities arrested four suspected members of a terror cell Saturday morning in that country 's North African territory of Ceuta , a quartet that Spain 's Interior Minister claimed were well-trained and well-prepared to attack . Those arrested were two pairs of brothers , Interior Minister Jorge Fernandez Diaz told reporters Saturday . `` What is especially noteworthy with the breakup of this cell are the many parallels with the attacks in Paris recently carried out against the Charlie Hebdo magazine , '' Fernandez said , referring to the January 7 massacre that ended with 12 dead . Ceuta is a tiny , 7-square-mile Spanish exclave bordering Morocco , across the Strait of Gibraltar from Spain . The suspects , who are Spanish citizens and are of Moroccan origin , are `` strongly radicalized '' and had psychological and physical training , as well as training in the use of weapons , said the minister while addressing reporters at an event of his ruling conservative party . `` ( They were ) willing to carry out an attack , '' Fernandez said . `` And , according to the police , to blow themselves up .
