Amid conflicting reports Friday about casualties among foreigners who were taken hostage at a natural gas complex in Algeria, the government and JGC Corp. confirmed the safety of seven Japanese workers but said 10 others were still missing.

A senior official said one of the Japanese workers from the Yokohama-based plant-engineering firm who were confirmed safe sustained some wounds, but they were not serious.

At first three JGC workers were confirmed safe. Then on Friday evening, a company spokesman told reporters the JGC office in Algiers had confirmed that four more were safe.
