SINGAPORE: The public is advised to stay away from portions of beaches on Kusu and St John's Islands.

The waters there are affected by the oil spill from a recent collision of two oil tankers at East Keppel Fairway, south of Marina South.

As a result, the National Environment Agency (NEA) said 200 metres of the beach at Kusu Island and 100 metres of the beach at St John's Island are closed until further notice.

This is to facilitate the cleaning up of the beaches.

NEA said it will continue to monitor the water quality, and will inform the public when the beaches are re-opened.

In a statement on Tuesday, the Maritime and Port Authority of Singapore (MPA) said there have been significant improvements to Singapore's port waters, except for minor oil patches in the vicinity of the Southern Islands, and a few patches of oil at Pulau Seringat shoreline.

MPA said it will continue to work closely with the NEA and the Sentosa Development Corporation on the clean-up operations.

MPA is monitoring the situation in case there are undetected patches of oil.

Members of the public who spot any oil patches in the waters or coastlines can also contact MPA's 24-hour Marine Safety Control Centre at 6325-2488/9.

Vessel traffic in the Strait of Singapore and port waters remain unaffected. Port operations are also not affected.
