One dead as cargo ships collide off Tokyo

The Panama-registered Beagle III sank after hitting South Korea's Pegasus Prime in the early hours of Tuesday.

Japan's coastguard said that 11 Chinese crew members were rescued from the Beagle III, but another man died and eight more were unaccounted for.

The South Korean crew were all safe after the collision, the cause of which was not clear. Two helicopters and 19 patrol ships were dispatched to search for the missing men, the coastguard said.
