Fire crews were called to the scene of two large grass fires in Olney earlier this afternoon.
The fires were at River Meadow off Church Street, Olney, Milton Keynes.
A Bucks Fire and Rescue spokesperson said: "Crews are currently attending two large grass fires in Olney, near Church Street."
"Four fire engines are currently at the scene, and more are on their way."
Crews made "steady progress" and used water from the River Great Ouse in order to fight the fires.
The fire was in two adjacent fields.
Firefighters used a drone and extinguished the fire using haydrags and beaters.
