Specialist police are investigating suspicious packages found at three major transport hubs in London, Sky News reported.

Officers were called to Waterloo Station, Heathrow Airport and London City Airport in separate incidents within hours of each other earlier today.

Police are still assessing the situation at Waterloo and at City airport, but say a package found at Heathrow has been "made safe".

London City Airport was evacuated as a precaution, the Met Police said, but the airport has tweeted to say there is no impact on flights.

Train services at Waterloo are still running as normal.
