| Although the Israeli air force bombed the Phildelphi corridor along the border thousands of times during the course of the Cast Lead campaign, smugglers acknowledge that some tunnels running under the border between Egypt and the Gaza Strip have remained in use, and were in operation even during the fighting. Contrary to media reports, the Israeli air force apparently did not use more powerful bunker-busting bombs to destroy the tunnels, rather than regular explosives. Tunnels lined with wood reinforcement have been especially resistant to air force bombing raids. |
