In Alghero, a large spot in the protected sea, in front of Foradada Island, has alarmed some visitors to the park.
The visitors themselves, from the viewpoint, photographed the oily patch that stood out below the coast, in an area of absolute reserve, a few meters from the imposing limestone rock photographed by thousands of tourists.
It is difficult to establish whether it is liquid fuel leaked from some vessel or other chemical substances.
The anomaly was immediately reported to the competent authorities.
