Nearly half of all nursing homes for senile elderly people do not have proper fire protection measures, according to a government report released Monday.

Of the 8,259 buildings investigated at 7,963 group homes across the nation, 3,866, or 46.8 percent, were found in violation of the fire protection law, including not using flameproof curtains or not having fire extinguishers, according to the report compiled by the Fire and Disaster Management Agency.
