The Ground Self-Defense Force's information security unit conducted detailed surveillance on journalists and citizen and religious groups opposing the GSDF's operation in Iraq, the Japanese Communist Party alleged Wednesday when revealing what it claims are GSDF internal documents.

The documents include the names and titles of the targeted individuals and photos of antimilitary rallies, the JCP said.

"We have judged there is no doubt about the credibility of these documents," JCP leader Kazuo Shii said in a press release.
