KARACHI: Authorities have postponed an anti-polio campaign, scheduled to start in Karachi from Feb 4, due to law and order concerns in the metropolis.

Karachi EDO Health Dr Imdadullah Siddiqui said the campaign was postponed due to the city's deteriorating security situation and the non-availability of health workers.

The campaign was scheduled to start in Karachi and the rest of the province from Feb 4-6.

Siddiqui said that security personnel were busy assisting Election Commission workers in the voter verification process in Karachi, and were therefore currently unavailable to provide security to the health workers.

He added that polio workers constantly received death threats and could not initiate the campaign without adequate security.
