One person, who suffered fractures, has been hospitalised while six other passengers with minor injuries were discharged after first aid, airport sources said.

As the nose wheel has been damaged, recovery was taking time due to which the runway has been closed for 10 hours, Airport Director ACK Nair said. "We are trying our best to partially open the runway as early as possible," he said.
