Polio drives are conspiracy to sterilize Muslims: Militants
Attacks targeting polio teams were very frequent in Pakistan. Last month, a group of Pakistani polio workers was attacked by a school's administration in Karachi after the team attempted to vaccinate its students against the disease. Islamist militants oppose vaccination as they think these drives are a front for espionage or a conspiracy to sterilize Muslims.
