At least five people were killed in a shooting on the Ratodero-Jacobabad Road in Sindh on Saturday, according to police.
Police said the attack was linked to a long-standing feud between two rival groups of the Ghanghro clan.
The victims included a father and his two sons, another relative and a passerby. They were identified as Rajab Ali, his sons Qurban and Riaz, their relative Rajab Ghanghro, and passerby Abdullah Brohi.
The attackers fled the scene following the shooting, while police shifted the bodies to a hospital.
Sindh Inspector General of Police Javed Alam Odho took notice of the incident and sought a detailed report from the DIG Larkana.
The provincial police chief also directed authorities to use all available resources to identify and arrest those responsible for the killings without delay.
Police were investigating the circumstances surrounding the attack and searching for the assailants.
