If we assume that Al-Qaeda was behind the attack, it's hard to imagine how high-ranking Saudis weren't involved. Given what we know about Saudi funding of Al-Qaeda. Also, given what we know about CIA funding of Al-Qaeda, it's not a huge stretch to suspect US involvement. Or at least, a bungled entrapment or outright rogue operation. It's hard to guess what US allies might be involved. Israel is a popular guess. Especially given its oddly close relationship with the Saudis, and its entanglement with US intelligence agencies. And then there's the fact that Mossad agents were trailing the Saudi terrorists for some time before the attacks. But then, it could literally be anyone. And the Israelis and Saudis might have been framed.
