Twenty-six people were treated for breathing difficulties with two individuals taken to hospital following an alleged chemical incident at London City Airport.

The site was evacuated after a fire alarm went off in the terminal building. Passengers and airport staff were left on the tarmac as three fire engines responded to the alarm.

"Three fire engines and a range of specialist appliances have been called to reports of a chemical incident at London City Airport this afternoon," London Ambulance said in a statement.

Ambulance crews and the Hazardous Area Response Team attended to the incident.

The airport terminal remains closed with officials investigating the cause. Passengers have been advised to check with their airline for the latest information.

Images shared on social media Friday show crowds gathered outside the airport after the alarm rang at the busy airport in central London.



On Thursday, a 19 year old was arrested at a nearby tube station in North Greenwich after police carried out a controlled explosion.
