Bangladesh begins oil clean-up after spill

Bangladeshi fishermen, using sponges and sacks, have begun cleaning up a huge oil spill in a protected area that is home to rare dolphins, after environmentalists warned of an ecological "catastrophe".

Thousands of litres of oil have spilled into the protected Sundarbans mangrove area, home to rare Irrawaddy and Ganges dolphins, since a tanker collided with another vessel on Tuesday.

The tanker was believed to be carrying around 350-thousand litres of furnace oil at the UNESCO World Heritage site.
