KHAR, Pakistan (AP) - Officials say gunmen have killed a policeman who was guarding a polio vaccination team in north-western 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, Mr 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.
