London runway shut down after oil spill

London's Gatwick Airport says its runway has reopened after an oil spill caused its temporary closure, leading some flights to be delayed or diverted.

The airport, to the south of London, was forced to close the runway to departures and arrivals for about an hour on Monday after the spillage, meaning some inbound flights were diverted to other airports.

"There may still be delays, so please check with your airline for the latest information," the airport said on its website.

It has not said what caused the spillage.

Gatwick is Britain's second largest airport and is used by over 40 million passengers each year.
