NATO Supply Routes Through Pakistan:
- One route crosses the Khyber Pass and goes to Kabul
- The other route goes through Baluchistan province to Kandahar
- The routes carried about one third of NATO cargo for ISAF forces
- U.S. Defense Secretary Leon Panetta said the closure cost an extra $100 million a month in overland shipping through Central Asia
- Pakistan closed the routes after U.S.-led NATO airstrikes mistakenly killed 24 Pakistani troops near the Afghan border last November
