An emergency alert has been issued for part of Colorado because of a loss of containment at a nearby oil and gas facility.

Residents of Weld County were ordered to evacuate in the alert, issued by TV and phone, within half a mile of the town of Galeton.

The evacuation order, reported by CBS News Colorado, began at 11.40 p.m. on Sunday and ends on 1.40 a.m. on Monday.

Galeton Elementary School announced it would not open for classes on Monday, telling parents in a letter: “There was a loss of containment at a nearby oil and gas facility, and out of an abundance of caution the fire department is closing off sections of Galeton.”

This is a developing story and will be updated.
