The music video for Kanye West's 'All Of The Lights' has sparked concern that its flashing images may trigger reactions in sufferers of epilepsy. 

It only premiered on video hosting site Vevo this week, but has already racked up over 5 million views although today (February 24) is 'currently unavailble' through both YouTube and Vevo. 

Epilepsy Action explained that the video could cause problems for victims of the photosensitive condition, and that foundation's spokesperson Aimee Gee said:

"We are deeply concerned that this video may be harmful to some people with photosensitive epilepsy."

"We are doing all we can to warn people who may be affected not to watch it."

The video has been removed from its official channel at the moment, but you can still watch 'All Of The Lights' here:
