Army aims to close Gaza tunnels

Egypt's military has begun an operation to shut a network of smuggling tunnels under the Gaza border following an outbreak of tension with Israel.

Hundreds of tunnels snake under the border.

Israel says that Gaza's Hamas rulers bring weapons, ammunition and rockets through the tunnels and use them to smuggle militants out. Officials said that this week, three mechanised sensors were activated to identify the tunnel locations and also to mark them out for destruction. AP
