The marine environment is under threat again as a tanker carrying up to 90,000 tonnes of crude oil is leaking off the coast of south Wales.
It's thought only a small amount of oil has escaped from the 10-year-old ship but coastguards are trying to find out how serious the pollution is.
Meanwhile, anti-pollution ships are trying to vacuum some of the oil from the tanker Prestige that sank off the Spanish coast last week.
A precautionary ban on fishing has been extended to cover 310 miles of affected coastline.
