Two policemen guarding a polio vaccination team have been shot dead by gunmen in north-west Pakistan.
The team of two vaccinators was unharmed, police said.
Local polio vaccination teams are often targeted by anti-vaccine militants, some of whom claim vaccination is a Western plot to sterilise Muslims.
Pakistan and Afghanistan are the only countries where polio, which in severe cases can be fatal or leave patients paralysed.
The two gunmen had been hiding near a small water channel before opening fire on the guards from a “very close range”, local police said. END.
