At least 10 people are believed to have died after a fire broke out Saturday in south Dublin in Ireland, according to reports. Authorities have launched an investigation into the incident.

Emergency services were called to the site on the Glenamuck Road early Saturday. Two adults and two children suffered injuries and were rushed to a local hospital, BBC reported. Irish police have reportedly not confirmed the number of dead.

No immediate information about the deceased was provided, but, reports said they were from two separate families. According to, a couple and their five children were among the dead.
