A government source has identified one of the two Japanese nationals injured in Tuesday's terror attacks in Brussels as Yu Takita, who was hospitalized with serious injuries sustained in the subway blast.

Takita, who is in his 30s, is believed to be at a Brussels hospital after staff earlier in the day said they were treating a critically injured Japanese man who is in a coma.

While it has not been confirmed, another government source said there were only two Japanese nationals with confirmed injuries and Kyodo has interviewed the other victim.
