Spanish fishermen are staging a protest in disputed waters between Gibraltar and Spain.

Arguments started when an artificial concrete reef was placed on the sea bed.

Spanish fishermen say the concrete reef restricts their right to fish, but Gibraltar says it will help sea-life.

The territory has been the cause of tensions between Britain and Spain for some time.
