Three die in attacks on polio teams
Gunmen have killed a polio worker and two policemen assigned to protect health teams in northwest Pakistan.
No group claimed responsibility for the attacks, but Pakistani militants have killed more than a dozen polio workers and police protecting them over the past year. They accuse health workers of acting as spies for Washington and claim the polio vaccine is intended to make Muslim children sterile.
In the first attack on Friday, gunmen opened fire on two officers as they were riding on a motorcycle to the town of Swabi, north-east of Peshawar.
Hours later, a gunman killed a polio worker on his way home after vaccinating children near Peshawar.
Pakistan is one of only three countries where the virus is still endemic. Militants have targeted workers vaccinating children, policemen escorting polio teams in the tribal and urban areas in the northwest and elsewhere, and have also threatened people who want to get their children vaccinated.
