Pak cop killed in anti-polio attack

A Pakistani policeman was shot dead and another was wounded yesterday while escorting a polio vaccination team in the country's northwest, local officials said.
No one has claimed responsibility for the killings, but the Pakistani Taliban last year banned polio vaccinations in the tribal region of Waziristan, alleging the campaign was a cover for espionage.
Wednesday's killing happened in the Parhoti neighbourhood of the town of Mardan on the second day of a three-day local anti-polio campaign.
