The BBC are reporting that King's Cross railway station has been evacuated over fears a fire in a nearby building may spark an explosion.
There's currently a 200m exclusion zone around the construction site near the station which caught fire at around 8:30 this morning. The station was evacuated at around 11. One person has been taken to hospital with burn injuries.
East Coast main line operator GNER was forced to turn around trains at Peterborough, while First Capital Connect trains on the Thameslink line were turning round at Finsbury Park in north London. Hull Trains' services were also affected.
The tube is unaffected.
