Tokyo ? Survivors of the U.S. firebombing of Tokyo during World War II and bereaved family members sued the Japanese government on Friday for $10.3 million, alleging it did not assist victims in the aftermath.

Friday’s action is the first group lawsuit of its kind seeking damages from a wartime air raid in Japan, Japanese media said. The raid on March 10, 1945, incinerated wide areas of the capital and killed 100,000 in a single night of fire.

The group filed the suit in Tokyo District Court, court spokesman Yoichi Sakamoto said. He refused to provide any other details.

The 112 plaintiffs in the lawsuit allege the government neglected providing aid to raid victims and accused Japan of starting the war and inviting the attack by refusing to surrender, Kyodo News agency said.
