A Libyan crude tanker spilled some of its cargo off Singapore after colliding with another ship on Friday, Bloomberg TV has reported. About 4,500 metric tons of crude were spilled, according to the Maritime and Port Authority of Singapore. The Alyarmouk, owned and registered in Libya, collided with the Sinar Kapuas, a dry-bulk ship, in waters northeast of Pedra Branca island, the port authority said on its website today. One of the Alyarmouk's tanks was damaged in the incident, resulting in the leak. No injuries have been reported.
