From CNN world news:
The al-Eqtisadiah daily said firemen scuffled with members of the religious police, also known as "mutaween," after they tried to keep the girls inside the burning building because they did not wear head scarves and abayas (black robes) as required by the kingdom's strict interpretation of Islam.
The English-language Saudi Gazette, in a front-page report on Thursday, quoted witnesses as saying that members of the police, known as the Commission for the Promotion of Virtue and Prevention of Vice, had stopped men who tried to help the girls warning "it is a sinful to approach them."
Surely it must also be considered sinful to force girls into staying in a burning building causing them all to die
I know many religions have strict rules which much be obeyed but that is just crazy.
