IDF planes finished this morning, Sunday, demolishing a terror tunnel that passed under the Kerem Shalom Crossing from Gaza into Israel.

The IDF says with certainty that the tunnel belonged to Hamas.

The tunnel started in the Rafiah area 900 meters (2,953 feet) into Gaza and extended 180 meters (591 feet) into Israel. It passed under the gas pipeline between Egypt and Gaza.

IDF Spokesperson Ronen Manelis says that the tunnel was located several days ago.

"Last night, we carried out a professional and precise operation over a blatant violation of Israeli sovereignty," Defense Minister Avigdor Liberman said in a statement. "The demolition of the attack tunnel system is an important factor in the policy of systematically harming Hamas' strategic ability. The message to Gaza leadership and its residents is clear: Invest in the sanctity of life, and not in burial tunnels."

Last night, it was reported that Air Force planes on Friday night had attacked "terrorist infrastructure" in southern Gaza, near the Gaza-Egypt border.

"The Hamas terror group is responsible for everything which occurs in Gaza and comes from Gaza," the IDF said in a statement.

This is the third tunnel blown up in recent months, leading experts to conclude that the IDF has found a new and undisclosed method of locating and destroying the tunnels, Hamas' newest attempt to invade Israel. Kulanu MK Yoav Galant, former head of the IDF Southern Command, explained on Galei Yisrael radio that the Iron Dome has made rocket launching ineffective, the sea blockade prevents weapons fromm arriving by ship and now the tunnel invasion idea is on its way to oblivion.
