MADRID (Reuters) – Spanish police have arrested two people in Spain’s North African enclave of Ceuta accused of connections with Islamist militants, the Interior Ministry said on Friday.

The two detained had been through a long radicalization process and formed part of a group which was thought to be at an advanced stage of preparation for potential attacks, it said.

Police, searching six locations in relation to the arrests, found one gun and three non-firing weapons, the ministry said, though it did not elaborate.

Police had unearthed at least one automatic weapon wrapped in a plastic sheet on wasteland near the locations being investigated, a Reuters witness said.

Spanish police have arrested 180 people accused of connections to Islamist militant groups since raising the country-wide security alert to one below the highest level in 2015.
