Spanish police have detained six militants suspected of recruiting fighters for Mali and Libya, according to the interior ministry.
The arrests took place in the enclave of Melilla, one of two Spanish cities in mainland Africa that shares a border with Morocco.
One Spanish militant who had been to training camps run by the Movement for Unification and Jihad in West Africa (MUJAO) was among those arrested in the ongoing operation.
In March, police from Spain and Morocco broke up a similar cell which had been sending fighters to conflict zones such as Syria.
Seven people were arrested during the joint operation, including two French nationals.
