“Two people were killed and 13 wounded Monday in a bombing that targeted polio workers in northwest Pakistan, police said,” CNN reports (10/7). “The attack took place on the third and last day of a U.N.-backed vaccination campaign in a suburb of the city of Peshawar, police said, adding that a policeman was among the two dead,” Agence France-Presse writes (10/7). “During these vaccination campaigns, teams of polio workers often accompanied by police escorts go door to door in villages and towns to administer the vaccinations,” according to the Associated Press/Fox News. “The campaign targeted Monday had originally been scheduled for September, but was delayed over security concerns, said a health official,” the news agency adds (10/7). “Pakistan is one of only three countries where polio remains endemic, due in part to militant resistance to polio mass vaccination campaigns,” BBC News notes (10/7). “Eight new cases of polio were reported in Pakistan last week, according to the Global Polio Eradication Initiative,” Reuters reports (Houreld, 10/7).
