Worker at Japan's wrecked Fukushima nuclear plant dies from injury amid growing accidents

A worker at Japan's wrecked nuclear power plant has died after his head got stuck in a hatch on the back of a septic tank truck while inspecting the vehicle, the latest accident at a site still struggling with the cleanup of the 2011 Fukushima disaster.

The operator of the Fukushima Dai-ichi plant says the 52-year-old worker was pronounced dead at a nearby hospital after his colleague, who operated on the hatch from near a driver's compartment, found him slumped at the back of the vehicle Saturday.

The operator, Tokyo Electric Power Co., says the cause of the accident is unknown and police are investigating.

The plant's decades-long decommissioning involves thousands of workers. The number of injuries last year doubled from a year earlier.
