Spanish police broke up a terrorist cell early Wednesday morning, less than three weeks after another terror cell murdered 16 people in a pair of attacks in Barcelona and Cambrils.

Six people were arrested from the cell, which authorities believe may be affiliated with the ISIS terror organization.

Authorities in Spain say the Moroccan government assisted in the investigation which led to the arrests.

One of the suspects was captured in Melilla, a Spanish enclave on the North African coast. Five others were nabbed in Morocco.
