CAIRO (Ma'an) -- Egyptian forces on Saturday discovered and destroyed a 1.5 kilometer smuggling tunnel beneath the Gazan border, the Egyptian army said.
Egyptian security sources told Ma'an that the tunnel was found by Egyptian border guards in the Dayniya area south of Rafah.
They said that eight sacks of explosive TNT material and a half-ton of C-4 -- another explosive material -- had been found inside the tunnel. Both the tunnel and the explosive material were destroyed by the army.
Smuggling tunnels have served as a lifeline to the outside world for Gaza's 1.8 million inhabitants since Israel imposed a crippling siege on the coastal enclave in 2007, which is supported by Egypt.
While the tunnels are used by Hamas as a source of tax revenue and inflow of weapons, they also supply highly-demanded necessities for Gazans including food, medicine, as well as infrastructure materials including concrete and fuel.
Egypt has sought to destroy the tunnels as part of an ongoing security campaign in the northern Sinai against anti-regime militants launching attacks on Egyptian police and military personnel.
