MULTAN: Six people were killed and 22 were injured in a clash between the Khetran and Marri tribes in the border area of Dera Ghazi Khan district on Friday evening. Abdul Rehman Khan Khetran, the chief of the Khetran tribe and former provincial minister said, "We have decided to take revenge on the Marri tribe because law enforcement agencies had failed to take any action against them after they created trouble by hitting electricity poles with rockets and missiles in Barkhan and Kohlu districts." He said that the Marri tribe retaliated when it was attacked, resulting in the death of 6 people from both sides. "The injured have been taken to a hospital in Dera Ghazi Khan," he added.
