Firefighters have been called to rescue two people trapped inside their cars following a crash in Rackheath.
A black Kia Venga and white Citroen C4 Picasso crashed shortly before midday today on Wroxham Road, at the junction with Swash Lane.
It is understood that one of the vehicles was on its roof.
An ambulance service spokesperson said one elderly patient was flown to the Norfolk and Norwich University Hospital with a rib and arm injury.
A second person was taken to hospital by land ambulance.
Norfolk Police said Wroxham Road is closed from Green Lane West through to Dobb's Lane. An air ambulance has also been called to the scene.
Fire crews from Earlham and Stalham used hydraulic rescue equipment to free two people from their vehicles.
In a Twitter post, PC Jon Parker said: 'Colleagues attending serious RTC at A1151 Rackheath near the Green Man. Road totally blocked. Avoid area.'
