ISLAMABAD (AP) — Pakistan has detected a record number polio case already this year, a senior government official said Saturday, as militants target vaccination teams and accuse doctors of being spies and sterilizing boys.

With the confirmation of polio virus among eight more children from the northwest and southwestern city of Quetta and port city of Karachi, Pakistan broke its own 14-year-old record of highest cases in a year, said Rana Mohammad Safdar, a senior official at the National Institute of Health in Islamabad.
