The rebel, who identified himself as Senad el Sadık el Ureybi, said: "We grabbed him, I hit him in the face. Some fighters wanted to take him away and that's when I shot him twice, in the head and in the chest."
He noted that Gaddafi didn't die instantaneously, and that it took half an hour. He said he didn't like the idea of Gaddadi being caught alive.
The video also shows a bloodied shirt which allegedly belonged to the dictator and a golden ring with his wife's name engraved on it. The claims cannot be confirmed as of yet.
