The number of attacks this week on polio workers is unprecedented. They came as the government started a three-day vaccination drive Monday targeting high risk areas of the country, part of an effort to immunize millions of children under the age of five.
The deadliest of Wednesday's attacks occurred in the northwestern town of Charsadda, where the female polio worker and her driver were gunned down, said senior government official Syed Zafar Ali Shah. Gunmen attacked two other polio immunization teams in Charsadda and one in the town of Nowshera, but no one was hurt in those attacks, he said.
Earlier in the day, gunmen shot a polio worker in the head in the city of Peshawar, wounding him critically, said Janbaz Afridi, a senior health official in surrounding Khyber Pakhtunkhwa province.
On Tuesday, gunmen killed five female polio workers—three of them teenagers—in a series of attacks in Karachi, the capital of southern Sindh province, and a village outside Peshawar. Two men who were working alongside the women were critically wounded in those attacks. A male polio worker was also shot to death in Karachi on Monday.
Police conducted two operations in Karachi in the wake of the shootings in which they arrested a dozen suspects and killed two suspected militants, said senior police official Shahid Hayat.
