Over 250 export-bound garment containers are stuck at Pakistan's Karachi International Container Terminal (KICT) after problems with security scanning facilities led to a backlog.

Karachi is Pakistan's only operational seaport and handles more than 90% of the country's import and export activities, in addition to Afghanistan bound NATO supplies where security scanning is a major issue.

The delays have caused a slowdown in the outward movement of garment shipments from Pakistan to the US and EU.

Many consignments are also stranded in various cities across the country, due to the shortage of containers and transport facilities linked to the port backlog.

Arshad Jamal, senior vice president of the All Pakistan Customs Agents Association (APCAA), blamed authorities for causing unnecessary delays in container clearance over the past year - which has put a financial burden on exporters.
