Firefighters are tackling a large blaze at an industrial site in Paddock Wood.
Crews were called to Eldon Way just at 3am this morning. People living nearby are being advised to keep windows and doors closed because of thick black smoke.
Crews say they are making good progress and there are no reported casualties.
But heavy smoke in the area is likely to impact on trains running on the nearby train line.
Southeastern say services are now running but passengers are likely to face delays.
