Update 2.25pm: The crew of a transatlantic flight which diverted to Shannon Airport with an ill passenger this afternoon reported an issue with a fuel valve before landing.
An inspection of the runway was carried out after the emergency landing, during which it was confirmed that landing strip had been contaminated with aviation fuel.
Ground crews quickly set about dealing with the spilled aviation fuel - however operations at the airport had to be suspended for almost two hours.
An airport spokesperson confirmed: "In addition to the medical case the aircraft also reported a fuel valve issue which resulted in fuel having leaked on to the runway and taxiways.”
"For safety reasons Shannon Airport temporarily suspended aircraft movements until the contamination was removed. The runway reopened at 2pm,” the spokesperson confirmed.
