This time last month, Mohamed Salmi says he was just another anonymous foreigner living and working in Japan. Today he fears his life here may be over, and receives phone calls from reporters asking him if he is an al-Qaida "terrorist."

"I've no idea why they have picked on me," says the Algerian, who has lived and worked in Japan for over 20 years and is married to a Japanese national. "My wife and I are still struggling to believe it."

Salmi's name was one of several released in extraordinary leaked documents from a counterterrorism unit of the Tokyo Metropolitan Police Department's Public Security Bureau. Listed as "terrorist suspects," the men are Muslims who live and work here, in many cases for decades.
