"I saw seven dead that I filmed. There were four attackers. I was swimming when it started and I ran away," said Dramane Kima, who showed the video of the bodies to Reuters.
He also took pictures of grenades and ammunition clips that he believed had been left behind by the attackers.
The assailants, who were "heavily armed and wearing balaclavas, fired at guests at the L'Etoile du Sud (Southern Star), a large hotel which was full of expats in the current heatwave," a witness told AFP.

Analysts have voiced fears attacks could spread to countries such as Ivory Coast and Senegal, and the region's US-led Flintlock military exercises that wrapped up recently focused on the need to counter extremism.
Home to some 80,000 people, Grand-Bassam holds UNESCO World Heritage status thanks to its elegant colonial-era facades.
