Reports from China suggest war crime evidence found

Reports from China say that researchers have found second world war Japanese documents about people arrested and experimented on by the occupying Japanese army.

The Xinhua news agency says that thirty-one volumes of documents, with biographical details and photographs were uncovered: some are said to contain instructions that more than three thousand people be sent to a special unit for germ experiments.

Xinhua says that experts believe the documents found in the eastern city of Harbin are the first of their kind written in Japanese to be found in China.
