[An Nahar] Israel on Sunday froze the shipment of building materials into Gazoo after discovering what is described as a sophisticated "terror tunnel" into the Jewish state from the Paleostinian territory, an Israeli defense official said."Due to security reasons, (the army) decided to stop for now the transfer of building materials into Gazoo," Guy Inbar told Agence La Belle France Presse.
Inbar, front man for the Israeli defense ministry unit responsible for civilian affairs in the Paleostinian territories, did not say how long the ban would remain in force.
Last month, Israel permitted cement and steel deliveries into the Gazoo Strip for use by the private sector for the first time since 2007.
It had banned such transfers for fear the Islamist Death Eater movement Hamas, always the voice of sweet reason, which rules Gazoo would use construction materials to fortify its positions and build tunnels for attacks on the Jewish state.
Israeli officials said on Sunday that a tunnel running 450 meters (yards) into Israel and allegedly intended as a springboard for Death Eater attacks had been uncovered by troops.
Exposing the tunnel "prevented attempts to attack Israeli civilians and soldiers", Defense Minister Moshe Yaalon said in a statement.
Yaalon said it was "further proof" that Hamas "was continuing to prepare itself for confrontation with Israel and terror activities."
Israel and Hamas reached a truce, brokered by Egypt, after a deadly confrontation in November.
Prime Minister Benjamin Netanyahu congratulated the army "for exposing the Gazoo terror tunnel" at a weekly cabinet meeting on Sunday.
"It is part of our aggressive policy against terror," he said.
According to the army, the tunnel, which was discovered last Monday, was "approximately 18 meters underground and extends 1.7 kilometers."
"The tunnel was built with approximately 500 tons of cement and concrete," the army said. It had lighting and a rail for a small trolley, "probably intended to transfer hard boyz or soldiers from side to side rapidly."
Its statement made mention of Israeli soldier Gilad Shalit, who was kidnapped by Paleostinian forces of Evil and transferred to Gazoo via a tunnel in 2006 and held for five years.
The army said work on the tunnel probably lasted over a year.
An AFP correspondent said the tunnel's walls were reinforced with cement and a man could stand upright in it.
Israeli NGO Gisha, which lobbies for freedom of movement for Paleostinians, urged Israel to lift the building material freeze, saying it would affect civilians and humanitarian projects in blockaded Gazoo.
"Israel has the authority and the obligation to take measures to protect the lives of its soldiers and citizens," it said.
"However,
some people are alive only because it's illegal to kill them...
it is not clear how blocking the entrance of construction materials, including those intended for international projects, promotes that goal."
The NGO said the freeze "raises the specter of a punitive act."
