Spain's interior minister called for calm on Friday after residents of Ceuta clashed with police during protests against migrants who have remained in the north African enclave after July's mass crossing.
Tensions have been high in the territory of 80,000 people since at least 60,000 people crossed into Ceuta in a few days in July setting off a Europe-wide migrant alert.
The Spanish government says most have since left the enclave of 18.5 square kilometres (seven square miles) again but thousands remain wandering the streets and sleeping on beaches.
Demonstrations have grown in recent days and some protesters clashed Thursday with police on a beach where migrants have been sleeping. Some of their belongings were burned.
A soldier was injured in a separate incident Thursday when migrants threw stones at troops and 12 Moroccans migrants were arrested. Two more arrests were made when migrants attacked a police officer, sources said.
