Buffalo attacks lion cubs- rare footage (watch till the end)

This happened in Masai Mara where we saw a buffalo grazing near a pride of lions. There were 3 lionesses present (no male) and around 7 cubs. The pride was resting on the cliff above and looked wary of the buffalo. Next thing we know, the Buffalo started coming up the banks to go after the cubs as the mothers tried to distract it. A very rare sighting in Masai Mara.
