The IDF discovered a tunnel along the Gaza Strip border on Monday, apparently to be used to carry out an attack inside Israel. This tunnel is one of the longest uncovered in recent years and is similar to the one used for kidnapping Gilad Schalit.

Shalit, an Israeli soldier, was released by Hamas in October 2011 after more than five years in captivity in exchange for some 1,100 Palestinian prisoners, many of whom reportedly returned to participating in terror activities.

The tunnel, which was discovered Monday near Kibbutz Nir Oz during a regular patrol near the border with Gaza, was built with the intentions to conduct terror attacks against Israeli civilians and soldiers, the Israel Defense Forces said in a statement.

The military sources claim that investigations would continue over coming days. It is not clear when the tunnel was dug and if it was used. It is believed that the tunnel collapsed due to recent rainy weather.

"We view this incident gravely," the IDF Spokesperson's Unit said. "This represents an attempt to conduct terrorist activity against civilians and security forces in Israeli territory."

The terror tunnel was revealed thanks to last week's heavy rains throughout the region.

Palestinian terror groups, including Hamas, have called for the kidnapping of more Israeli soldiers in order to exchange them for Palestinians in Israeli jails.
