The attack, which has also left seven police officers injured, was one of the deadliest on police in recent years.
At least 11 police officers have been killed during an ambush by armed attackers in eastern Pakistan, according to local officials.
The attackers were armed with guns and rocket-propelled grenades (RPGs), police said, and seven other officers were injured.
The convoy of officers was targeted in Pakistan’s eastern Punjab province, in the Rahim Yar Khan district.
The convoy was passing through a deserted area as part of an operation targeting robbers in the region, Punjabi police said in a statement.
Pakistan has witnessed a surge in attacks by militants in recent years, but such a high number of police casualties in a single attack is rare.
Pakistani security forces often carry out operations against bandits in the eastern Punjab and southern Sindh provinces, where they hide in rural, forested areas.
