JERUSALEM (JTA) — The Israel Defense Forces uncovered a tunnel from Gaza into Israel.

The tunnel is the first to be discovered since Operation Protective Edge, the summer 2014 Gaza War, according to the IDF. Its discovery was announced on Monday by the IDF, which worked in conjunction with the Shin Bet security service.

The IDF said in a statement that the tunnel was built by the terrorist organization Hamas ” in order to infiltrate Israel and execute terror attacks against the people of the southern communities.”

“The IDF will continue its counter terror efforts to uncover and neutralize Hamas’ offensive tunnels,” the statement said.

Since its discovery, the IDF has destroyed the tunnel openings on both the Israeli and Gaza sides.

The tunnel began in a southern Gaza residential neighborhood, according to Haaretz. On the Israel side it is located between the border fence and Israeli military bases, and was about 100 feet below ground.

It is not known when the tunnel was constructed and how many branches it has.
