At least eight people including a brother of the serving member of the Balochistan provincial assembly, Manzoor Kakar, were injured during an exchange of fire at Quetta's Jinnah Road on Wednesday evening.

Police officials said the firing took place between two armed groups as a result of a property dispute. Naseer Kakar, the brother of MPA Manzoor Kakar ─ who belongs to ruling coalition partner Pashtoonkhwa Milli Awami Party (PkMAP) ─ was driving his brother's car when his vehicle was attacked.

The injured were rushed to Civil Hospital Quetta for medical treatment where the doctors described the condition of one of the injured persons as serious.

Later police arrested Naseer Kakar along with his guards.

"My vehicle was attacked but I was not inside the vehicle", Manzoor Kakar told DawnNews. He said his brother was also injured as result of the firing.

Police and other law enforcement agency personnel reached the crime scene and an investigation into the incident has started.
