Story highlights Interior minister: "They were willing to carry out an attack"

2 pairs of brothers arrested in Spanish territory of Ceuta

Minister: They had similarities to those behind the Charlie Hebdo massacre

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.
