KHAR, Pakistan (AP) -- Officials say gunmen have killed a policeman who was guarding a polio vaccination team in northwestern Pakistan.
Local government administrator Faramosh Khan says the gunmen attacked the team on Monday in the town of Mamound in the Bajur tribal area, just as it had started a vaccination drive.
No one has claimed responsibility for the shooting, but suspicion will likely fall on Islamic militants suspected in similar attacks.
A senior regional health official, Jehanzeb Dawar, said a total of 624 teams are taking part in the latest push in Bajur to vaccinate over 220,000 children. The teams re-launched the drive after taking a couple of months off because of past attacks on vaccination teams in the country.
It's unclear whether the campaign will continue after Monday's attack.
