Gunmen on Wednesday opened fire on a polio team in Mardan district of Khyber Pakhtunkhwa, killing one policeman and injuring another.
The police had resumed guarding the teams after an incident in February in which a policeman was shot dead while protecting a polio vaccination team on the outskirts of Mardan.
As a result of today’s attack, the anti-polio drive in the region has been suspended.
Pakistan, Afghanistan and Nigeria are the only countries where polio is endemic. Polio cases in Pakistan hit 198 in 2011, the highest figure for more than a decade and the most of any country in the world, according to the UN.
