A large amount of oil has been dumped at Mosta/Naxxar valley between last week and today, as can be seen from the You Tube videos embedded with this article.
Marcus Camilleri, who shot the videos this morning, told timesofmalta.com the oil was not there last week. He said he took the videos from between the Mosta and Naxxar valley, just below a quarry.
Mr Camilleri said that he called the Naxxar police station and the mobile unit were on site in less than five minutes.
