Cheetah brings tourists to a halt

A cheetah brought a tourist convoy driving through Kenya's Masai Mara National Reserve to a complete halt for 45 minutes by taking up residence on top of one of the Jeeps.

At first the big cat jumps up on the hood to get a good look at its surrounds, completely ignoring the gawping tourists, who all silently pull out their cameras.

Only when the Jeep starts to move again does it take the hint and jump back down. "Oh, I can breathe," one of the tourists says.
