A Netherlands-flagged ship struck a stationary vessel in Singapore, causing an oil spill that blackened the waters of the city-state’s popular beaches and prompted a huge cleanup operation along its southern shores.

       The Vox Maxima dredger reported a “sudden loss in engine and steering control before its allision” with the Singapore-flagged Marine Honour, a bunker vessel carrying fuel oil, on Friday, according to a statement Sunday by Singaporean authorities.
