PITTSBURG COUNTY, Okla. - Officials say five people are unaccounted for after a drilling rig explosion in Pittsburg County.

Multiple ambulances and three medical helicopters responded to the scene. However, it is unclear how many people were injured during the explosion.

Part of the rig collapsed in the explosion.

Officials say the fire continues to burn, but it appears to be contained.

The Oklahoma Corporation Commission confirmed to KJRH that "Red Mountain Energy LLC" out of OKC is the operator at this site.

The company says it was a drilling rig, but they are not sure exactly what it was drilling for.

Officials say the rig drills for natural gas and oil.

Oklahoma Emergency Management officials say they have contacted the Department of Environmental Quality and the Corporation Commission.
