Four suspected jihadists who allegedly formed a cell in Spain's north African enclave of Ceuta, have been arrested by police.
Interior Minister Jorge Fernandez Diaz said investigators were struck by the similarities between the suspected cell members with those who perpetrated the Charlie Hebdo attack in Paris.
"These are two pairs of very radicalised brothers who are highly trained militarily, physically and mentally and are prepared to carry out an attack, and ready, according to the police, to blow themselves up in the act," Fernandez Diaz said.
A ministry statement said the arrests were made early today and investigators were assessing the cell's "infrastructure to carry out terror attacks in the country".
Two houses in Ceuta were searched on instructions given by a judge and the state prosecutor attached to Spain's National Court, the statement said.
Spain and Morocco have arrested dozens of suspected jihadist militants and recruiters in recent years, especially around Melilla and Ceuta, both cities that are on the Mediterranean coast and surrounded by Morocco.
The identities of those arrested were not immediately available and the statement said the investigation was ongoing.
