Egypt has built an underground metal wall, with the stated aim of stopping the smuggling of weapons and goods through tunnels into Gaza.

It is an ongoing construction project, but it appears to have failed.

The tunnels are still operating – and that is because smugglers have found a way to break through the barriers, and supply people in Gaza with food and other essentials.
