YOKOHAMA (Kyodo) Prosecutors on Tuesday charged two Maritime Self-Defense Force officers in connection with the fatal 2008 collision between their destroyer and a fishing boat that claimed the boat's father-son crew.

Lt. Cmdrs. Keitaro Ushirogata and Tomohisa Nagaiwa were indicted without arrest over the collision, prosecutors said.

Ushirogata, 36, was the chief watch officer aboard the 7,750-ton Atago just before its predawn collision with the 7.3-ton Seitoku Maru in February 2008.
