Man lights American flag on fire at Cleveland protest - and it immediately backfires

A man who set an American flag on fire outside the Republican National Convention on Wednesday had his plan immediately backfire.

Cleveland Police said on Twitter that a protester "lit flag on fire" and then "lit himself on fire."

Footage posted to Twitter captured the chaotic incident on video.

"You're on fire! You're on fire, stupid!" a man could be heard shouting in the short clip.

The demonstrator was not injured, police said. At least two officers were assaulted and suffered minor injuries patrolling the protest.
