One man was killed and two others were seriously injured Sunday night in Osaka after being attacked by a group armed with knives and a baseball bat, police said.
The man who was killed was found late Sunday on a street in Ikuno Ward. The other two were found at a nearby condominium.
All three appear to be Vietnamese nationals in their 20s or 30s, the police said Monday. Their assailants may also be non-Japanese, they added.
