Emergency teams are working to contain a crude oil spill after a tanker and a bulk carrier collided in waters off Singapore.
Port officials say no injuries have been reported but the Malaysian-registered tanker has ruptured one of its tanks and an estimated 2,000 tonnes of crude oil are leaking into the sea.
The collision happened in the Strait of Singapore, one of the most important shipping lanes in the world, the BBC reports.
Singapore's Maritime and Port Authority said the Malaysian-registered tanker Bunga Kelana 3 was damaged in a collision with the MV Wally, registered in St Vincent and the Grenadines.
The Bunga Kelana 3 was carrying light crude oil and condensate.
Both ships are anchored off Singapore as work continues to contain and clean up the oil spill. AET, the Malaysia-based operators of the tanker said booms were being placed around the vessel to contain the spill.
Salvage operators said the oil could damage the local environment but that the speed of the response had reduced the impact.
There was no reported effect on shipping traffic in the Strait of Singapore, one of the world's busiest sea lanes, connecting trade routes from Asia to Africa and Europe.
