A 1,000 tonne oil slick is moving towards Ireland and the UK. It is believed to be from a Russian warship refuelling in the Celtic Sea.

The slick is expected to come ashore in two weeks.

A Russian destroyer, a British destroyer, an Irish Naval vessel and a Russian aircraft carrier are all at the scene of the spill about 50 miles south of Fastnet, off the west Cork coast, along with an ocean-going tug and two refuelling tankers.

The Irish government has asked the Russian embassy in Dublin to hand over samples of the oils carried onboard the Russian tankers and aircraft carrier, according to PA.
