Bizarre footage has emerged showing a tree burning from the inside with no smoke.

The unnerving video has prompted some viewers to speculate that the phenomenon is the work of the DEVIL.

Two hikers chanced upon the blaze while walking in Defiance, Ohio, last week.

One of the men filmed the sight on his mobile phone and posted the chilling clip to YouTube.

One of the hikers can be heard saying: "It’s starting to get up and around."

As the flames are seen licking inside the hollow tree, yet producing no smoke at all, one of the men exclaims: "What the f**k?! How is this even possible?”

His friend shouts: "We better get out of here."

The video was posted on December 21 and has been viewed more than 225,000 times.

Some viewers dubbed it "Devil Tree" while another YouTube user wrote "HAIL SATAN!"

Another joked: “JESUS IS THAT YOU?"

Other more plausible suggestions for the fire include a lightning strike.
