This is Buzkashi. A bunch of horsemen (I doubt they let women ride horses in this barbaric country) fight over a goat carcass. The sport is originally from Central Asian Turks who spread this sport throughout the region from Iran, Afghanistan, Pakistan and hence later on to the British. Maybe this is how the British got the game of polo? This doesn't look much like the game I've seen played down at the Santa Fe Horse Park with the polo pros.

It does look a long way from home, however.
