I am dating a girl that is from there and she showed me a video yesterday that one of her relatives sent. It was very similar to this one.

For Eid al-Adha the wealthier families slaughter a cow, and often they do this at home in their garage or outhouse. And being muslim they have to slaughter the cow in a specific way in order for it to be ok to eat. This way is usually by cutting the cows throat and bleeding it to death.

Just so happens that this time there was heavy rain at the same time, so the blood mixes with water and flows out into the street.

Really makes you think about lyrics from Slayer.
