Egypt to close Gaza tunnels
Hundreds of tunnels snake under the nine-mile border, where smugglers bring Gaza supplies and fuel limited by an Israeli blockade. Israel says Gaza’s Hamas rulers bring weapons, ammunition and rockets through the tunnels and smuggle militants out.
Officials this week said three sensors were activated to identify tunnel locations and mark them for destruction. Earlier efforts were confined to trying to close tunnel openings, as well as one failed effort to drive a steel wall deep into the sand.
