For almost a week now, there have been almost daily attacks on NATO's supply line through Pakistan.
The most spectacular of the attacks have destroyed dozens of trucks at a time. On October 4, some 60 trucks were destroyed in northern Pakistan.
That was just days after Islamabad shut down NATO's supply route through the Khyber Pass to Kabul. The government says it is keeping the key Torkham border crossing closed indefinitely due to public anger over a September 30 NATO air strike from Afghanistan that killed at least two Pakistani soldiers.
