A ship with 4,000 cars on board has sunk just south of Singapore after colliding with an oil tanker.
Singapore's Maritime and Port Authority (MPA) said the crash took place just before midnight on Saturday.
The four Korean and 16 Filipino crew members of the MV Hyundai no 105 were rescued.
The collision left a 50m x 20m hole in the car carrier's side. The MT Kaminesan, which was carrying 279,949 tons of crude oil was towed into port.
"Prior to the collision, warnings were given to the two vessels by the MPA's vessel traffic information service. The two vessels also communicated with each other," a statement from the port authority said.
The cause of the crash is under investigation.
Singapore is one of the world's busiest ports.
