A Canadian also held captive in Syria has said that freed Japanese journalist Jumpei Yasuda should not be criticized for doing his job.

Yasuda, 44, who returned to Japan late last month after 40 months of captivity, has been criticized by some for putting himself in harm's way by entering Syria alone. He was almost immediately taken hostage by a warring faction that then demanded a ransom for his release.

"I think it is very important for journalists and humanitarians to go to areas where a lot of people don't or can't get to," Sean Moore said in a telephone interview Thursday. "The truth has to be told somehow, and that is a journalist's job."
