The three Japanese civilians who returned home after being held hostage for over a week in Iraq are suffering from acute stress disorder, a psychiatrist said Wednesday.

This condition is not only a result of their ordeal, but has also been caused by the public criticism to which they have been subjected for putting themselves in harm's way, he said.

Satoru Saito, who heads the Family Function Institute, met with the three Sunday night at Tokyo's Haneda airport, immediately after they arrived there from Iraq via Dubai, United Arab Emirates, and Kansai International Airport.
