The final missing Japanese worker in the hostage crisis at an Algerian natural gas complex was confirmed dead Thursday from the remains of various victims taken to Algiers, bringing the total number of Japanese killed to 10 and dashing any hope of further survivors.

The 10th body identified was heavily damaged, according to a government source. Like the other nine, the man was an employee of Yokohama-based JGC Corp. It has yet to be determined how many of the hostages were slain by their captors or were killed when Algerian forces stormed the complex to retake the facility.

Chief Cabinet Secretary Yoshihide Suga told reporters Thursday night that a team of Japanese officials in the Algerian capital identified the 10th Japanese victim from among dozens of bodies of unknown nationalities brought from the gas complex in the Sahara desert.
