Gunmen opened fire on a polio vaccination team in northwestern Pakistan on Tuesday, killing a policeman who was providing security to the team, officers said.
The shooting happened in the Kala village of Swabi district, where a two-man team was administering polio drops to children.
"The team, after finishing the campaign in Kala, was heading towards a nearby village when three men armed with Kalashnikovs appeared from sugarcane fields and opened fire," Swabi police chief Abdul Rashid Khan told AFP.
A police official escorting the duo was killed but the two team members were unhurt and the gunmen escaped, he said.
"It seems the target was the policeman," Khan said.
On January 1, six women and a man working for a charity involved in polio vaccinations were shot dead in Swabi.
