A MAJOR blaze has devastated an infant school in Essex.

More than 30 firefighters are tackling the inferno at John Ray County Infant School, Notley Road, Braintree.

A total of 10 fire engines are now on scene after receiving reports of the blaze at around 4.20pm.

Hundreds of people have come out to watch the drama unfold.

Stacey Cosens added on the social media website: “John Ray Infant School’s roof has caught on fire. Large flames and plooms of smoke can be seen in the area.”

Roads in the area have been cordoned off, according to reports.
