"One took place at the three policemen who were escorting a polio team, the policemen were on foot when they were attacked," said the official, Ali Asif. "In the second incident, four policemen in a police van were targeted."
Tehreek-e-Taliban Pakistan (TTP) splinter group Jamaatul Ahrar claimed responsibility for the attack.
Sindh Home Minister Anwer Siyal said eight armed men carried out the attack.
"The policemen sacrificed their lives to protect the polio workers," he told a private TV channel.
