When this crossing opened it was the preferred Israel option for entry into the Southern Gaza Strip, the Palestine option was the Rafah crossing both within 2 clicks of each other. We opened the Rafah crossing first the Karem Shalom crossing was forced on the Palestine Authority to accept humanitarian supplies when the main supply crossing closed down because of threats. In the past construction supplies came through another crossing, but that was for supplies from Israel, supplies from Egypt would need a lot more scrutiny. This type of chemical analysis was not available at any Gaza crossing, but a version of it is available at most USA airport's these days. Take a look at the makeup of the wall in the pictures.
