SIOUX CITY, Iowa (AP) – Authorities say two frozen hydrants hampered efforts to extinguish flames that destroyed a mobile home in Sioux City. Firetrucks were sent to the mobile home park around 5 a.m. Wednesday.

Sioux City Deputy Fire Marshal Frank Fulton says firefighters couldn’t tap into the two frozen hydrants, so they had to go to a third hydrant farther away to get water. Fulton says the problem may have cost the residents more property than they would have lost otherwise.

The three adults and three children who lived in the home escaped safely.
