The man was apparently firing the gun out of celebration.
This shocking video uploaded to Liveleak Thursday night was reportedly taken at a wedding in Yemen.
It begins with a group of men dancing to Psy's "Gangnam Style" while one carries an AK-47.
As the song reaches its chorus the men start cheering and one begins firing the AK-47.
Chaos ensues after the gun stops firing as wedding goers begin screaming.
