The South Korean shipbuilder, the world's third-largest, said rescuers were searching for people trapped under debris after the 32-ton crane fell on a ship today at its shipyard on Geoje island. The company said the crane collided with another crane before it collapsed onto the ship.
All of those killed were workers hired by various subcontractors at Samsung. Three of those hurt suffered severe injuries.
The accident occurred as many around the world were joining May Day marches for workers' rights.
