The shooting happened on Saturday night in the city of Jalalabad in Nangarhar province, and was believed to be over a land dispute, the province’s governor Zaiulhaq Amarkhil said.

Five brothers and three of their male cousins were killed.

The incident is under investigation but initial information shows a land dispute has caused the incident,” Amarkhil told AFP.

Fareed Khan, a spokesman for Nangarhar police, confirmed the attack.

Afghanistan, like the rest of the Muslim world, is observing the holy month of Ramadan, when men gather every night to offer special prayers after fasting for the day.

Revenge killings are common in Afghanistan, where families seek justice by carrying out violent acts of

vengeance based on an ancient code of honour.

So-called blood feuds can last for decades, passing down through generations in a cycle of violence.
