Slick fear after tanker collision

Nearly 2,000 tonnes of oil has leaked from a tanker after it collided with a freighter in the Baltic Sea, say Danish officials.
The Baltic Carrier, with 30,000 tonnes of oil on board, was en route from Estonia to Gothenburg in Sweden when the accident happened on Wednesday night.
The collision ripped a 20-metre wide hole in one of the tanks of the double-hulled vessel, although German officials on Thursday said oil was no longer leaking from the tanker.
The accident occurred in the sea lane between the north German coast and the Danish island of Falster.
The cause of the accident is still not clear.
