A private jet skidded off the runway at Liverpool John Lennon airport early this morning.
The runway at the Merseyside airport was shut with flights cancelled or delayed.
Arriving flights were diverted to Manchester airport or cancelled.
The runway is expected to be closed until this afternoon.
An airport spokesman told the Liverpool Echo: “I can confirm that around 6am a private business jet with four people on board – three crew and a passenger – landed OK but then came off onto the grass. For whatever reason it has skidded off the runway.
“There are no injuries but because of where it has ended up we have had to close the runway.
“Passengers are advised to check with their airlines before travelling.”
The airport tweeted: “The airport is currently closed, please contact your airline for any further information on your flight.
“We will update you as soon as we have more information.”
