The UN has suspended an anti-polio campaign in Pakistan after two more health workers died in the latest of a spate of gun attacks.
Attacks in the Peshawar region killed a vaccination supervisor and her driver, and injured a student volunteer.
Coming after five deaths on Tuesday, the UN said it was suspending its three-day vaccination drive.
No group has claimed responsibility, but the Taliban have issued threats against the UN’s anti-polio campaign.
Pakistan is one of just three countries where the disease is still endemic.
The UN children’s agency Unicef and the World Health Organisation were suspending work on the programme nationwide after Wednesday’s bloodshed, said Unicef spokesman Michael Coleman.
The UN provides technical and financial support to employees and volunteers of the local health department who administer the polio drops.
The programme was halted in Sindh province on Tuesday after four female health workers were shot dead in the city, while another female worker was killed in an attack in Peshawar.
