Firefighters battle raging inferno at Sussex school after reports of explosion (PHOTOS, VIDEOS)

A massive fire has broken out a school in Sussex, southern England, with images emerging online showing large sections of the secondary school completely destroyed by the blaze.

According to West Sussex Fire and Rescue, 14 fire engines are currently battling the blaze which began at the Academy Selsey school just before 8am local time. Local reports say an explosion was heard at the scene.

It is not yet known what caused the blaze.

Images from the scene show thick plumes of smoke rising from the burning building.

In the aftermath of the fire, a police officer diverting traffic away from the scene was reportedly struck by a car, according to BBC Sussex.

The officer's injuries are not thought to be life-threatening.

There have been no other reports of any injuries, but residents living close to the scene of the inferno have been warned to stay away and keep their windows closed. 

Selsey Football Club has tweeted footage of nearby thatched cottages being sprayed with foam to prevent them from catching fire.

The school was opened in 1963 by the Duke of Norfolk and it is understood that students were due to collect their exam results soon. An update on the Academy Selsey Twitter page says that alternative arrangements will be made for the collection of results.
