CHAMBERS, Neb. (AP) – Authorities say a 93-year-old woman died in an explosion and fire at her home in northern Nebraska.

The Holt County attorney’s office says firefighters, medics and sheriff’s deputies were dispatched to the home near Chambers on Sunday evening. Investigators blamed the blast on a propane gas release inside the residence.
