A 31-year-old man from Kanagawa Prefecture was in critical condition Tuesday following Monday evening's bomb blast in central Bangkok.
Kota Ando underwent emergency surgery, a local hospital said. It reported that his internal organs were damaged, but that he was conscious and his condition was stable.
The bomb exploded at Erawan Shrine, a street-side religious monument at an intersection in one of the Thai capital's commercial districts. The explosion left at least 20 people dead and 125 injured.
