BELLEVUE, Neb. (AP) — Authorities say two schools in an Omaha suburb were briefly evacuated because people smelled what they thought was natural gas.

Bertha Barber Elementary and Mission Middle School in Bellevue were emptied around 9 a.m. Thursday as utility workers arrived to check on the reports. The workers gave the all-clear within an hour, so students and staffers returned to the school buildings.

A district spokeswoman didn’t immediately return messages from The Associated Press Friday.
