Animals have started to die. The water hyacinths on the two rivers have turned black. Some Golpata trees have gone under heavy layers of oil.

One local, Abu Jafar, spotted two animals -- a monitor lizard and an otter -- dead and smeared with oil along the banks of the Shela.

Meanwhile, the authorities pulled the sunken oil tanker ashore around 11:00am yesterday, some 30 hours after the accident. But all the 3.58 lakh litres of furnace oil the tanker had been carrying already spilled into the rivers and the adjacent cannels.
