Islamabad: Motorcycle-borne gunmen today shot dead a policeman providing security to health workers administering polio vaccinations to children in northern Pakistan, taking the toll in such attacks to nearly 20 in past three months.
The polio team was busy to administrate drops to children in the outskirts of Mardan, a main city some 120 northwest of Peshawar, when unidentified armed men opened indiscriminate firing, killing the policeman at the scene.
"No one from the polio team was hurt," a police officer said. The attackers fled after the incident.
