The law-enforcement personnel were on routine duty, when two gun-wielding men riding a motorcycle opened fire at the checkpost soon after Friday prayers.
Three personnel died on the spot while one survived the assault but died later of his injuries, officials said.
Rangers Director General Major General Bilal Akbar, while talking to reporters after the incident, said the assailants wanted to attack a nearby mosque but on seeing Rangers security, resorted to firing at the personnel.
“Perhaps the mosque and the affiliated madrassa were the target of the terrorists,” Akbar said.
He said four security personnel were on board a vehicle, while two each were on board two motorcycles at the time of the attack.
The Rangers DG vowed to apprehend those behind the attack.
The area has been sealed by security forces and a search operation is currently underway.
Rangers is currently spearheading a grand operation against criminal elements in Karachi.
