Islamabad: Two polio vaccination workers have been killed in north-western Pakistan in the latest of a spate of deadly attacks.
The shootings in the Peshawar region left a vaccination supervisor and her driver dead, and injured a volunteer. The deaths brought to eight the number of health workers killed in this week’s anti-polio drive. The three-day drive is now over.  No group has claimed responsibility, but the Taliban have issued threats against the UN’s anti-polio efforts.
The militants have accused health workers of working as US spies and say the vaccine makes children sterile.
Pakistan is one of just three countries where the disease is still endemic.
Coming after five deaths, the UN children’s agency Unicef and the World Health Organisation halted work in Sindh province in the south and Khyber Pakhtunkhwa in the north-west. The suspension was extended nationwide.
The UN provides technical and financial support to employees and volunteers of the local health departments who administer the polio drops. – AP
