The fire started on the third floor around 4 pm and spread up to the sixth floor.

Madhya Pradesh Medical Education Minister Vishvas Sarang told PTI that the fire has been brought under control and efforts are on to completely douse it.

The official said the Indian Air Force (IAF) helicopter would be reaching around 1.20 AM and if required it will also be pressed into service.

The building houses offices of various departments of the Madhya Pradesh government, prompting authorities to call in fire tenders from Army, AAI and facilities of oil companies, officials and the chief minister's office said.

Chief Minister Shivraj Singh Chouhan apprised Prime Minister Narendra Modi, Defence Minister Rajnath Singh and Home Minister Amit Shah about the fire and sought assistance for dousing it, an official said.

The prime minister has assured Chouhan of all possible assistance from the Centre for controlling the blaze, the official said.
