Pakistan - NATO Supply Traffic Is Slow at Border - NYTimes.com A week after Islamabad reopened United States and NATO supply lines to Afghanistan, only a handful of trucks have crossed the border, Pakistani officials said Wednesday. The officials blamed Pakistan's bureaucracy and the need for new customs clearances for the delays. Before the closing, 150 to 200 trucks carrying NATO supplies crossed the border daily. One company involved in the shipping said it was delaying sending its trucks across the border because of security concerns after protests against the decision to restart shipments.
