The Ukrainian Emergencies Ministry has published footage of its rescuers fleeing from a large fire whirl in the Chernobyl exclusion zone.

The agency has been tackling blazes near the defunct Chernobyl Nuclear Power Plant since last week, but have so far been unable to contain the fire.

The 30 km (19 mile) radius exclusion zone was set up around the plant after the 1986 nuclear disaster. The mostly-forested area of 2,600 km² (1,000 square miles) remains closed to the public due to being heavily contaminated with radiation.

The clip, which was uploaded by the ministry on its Telegram channel on Friday, captured the formation of a large fire devil that quickly started moving towards the firefighters, forcing them to jump into their vehicles and retreat.

“A Fire tornado: wind, dust and flames merge into one destructive force. That’s exactly how the blazes, which parts of the Kiev Region are constantly fighting in the Chernobyl exclusion zone, look,” the post read.

Satellites have recorded large plumes of polluted air with increased levels of carbon monoxide extending 170 km from the epicenter of the fire in the exclusion zone. Chernobyl is located around 94 km (60 miles) north of the Ukrainian capital, Kiev, near the border with Belarus.
