A gas tank has exploded at Hindustan Petroleum Corporation Plant in Unnao. Fire tenders have been rushed to the spot.
The explosion was caused by a leak in a valve.
Though no casualty has been reported as yet in the incident, several villages located near the plant have been evacuated and all roads leading to the site have been closed to the public.
"We have put the area in a five kilometre-radius on high alert," said a senior official.
