Hong Kong - Twelve crew members from a Chinese cargo ship are missing after it collided with a container vessel and sank just outside Hong Kong waters on Monday, authorities said.
The collision happened in the early hours of the morning near Po Toi Island which lies on the edge of Hong Kong's territory, a fire department spokesperson told AFP.
"Two cargo ships collided and one of them sank," a police spokesperson told AFP.
"Later one male was rescued and was sent to the hospital," she said, adding that rescue operations were underway to find the other crew members.
"There are 12 people missing," a fire department spokesperson told AFP, adding that they were crew from the cargo ship from mainland China which had collided with a container vessel.
The fire department spokesperson said the accident happened about 5km south of Po Toi, just outside Hong Kong maritime territory.
Hong Kong's waters are notoriously crowded. Hundreds of vessels, from wooden sampans to enormous container ships, ply the shipping routes that criss-cross the territory every day.
A collision in October 2012 between a high-speed ferry and a pleasure boat claimed 39 lives in the city's worst maritime disaster for over 40 years.
The tragedy shocked the Asian financial hub, one of the world's busiest ports, which prides itself on its good safety record.
