LOUISVILLE, Ky. (WDRB) -- A bus carrying Oldham County Middle School students back from a trip to Washington, D.C. caught fire in Washington County, Pennsylvania, just a few miles from West Virginia early Thursday. 

Oldham County school officials say everyone on board is OK.

According to a letter sent to parents, the bus was carrying eighth graders and was returning from a field trip to Washington, D.C. Here is the text of that note:

Good Morning this is a call from Oldham County Middle School. One of our eighth grade Washington D C field trip buses has had an incident. It was Mr Krafts bus number 3 and everyone is okay. The bus caught fire but everyone was removed from the bus and are all okay. They are being transported to a safe place until another bus arrives to bring them the rest of the way back to Oldham county middle school. Again, mr kraft is with the students and everyone is okay. If you have any questions please contact the school office at 222 1451.

Parents praised Oldham County officials for letting them know about the bus fire so quickly.  

According to an Oldham County school official, it happened around 6 a.m. We're told there were 50 kids and five adults on the bus when the driver smelled smoke coming from the engine and pulled the bus over just before it caught fire. The bus was one of three taking part in the field trip. 

Heather Abraham with KDKA-TV in Pittsburgh, tells WDRB's Toni Konz that the bus caught fire on I-70, just a few miles from the West Virginia line.
