Construction work can be seen on the Israeli side of the border with the Gaza Strip, Israel March 18, 2018. Israel has since been developing detection technologies and laying down an underground frontier wall which, it says, will end the Gaza tunnel threat by 2019.
The laboratory has accomplished proven achievements in locating and thwarting five terrorist tunnels in recent months by combining the capabilities of the engineering, intelligence and the technological front, noted the IDF.
It comes a day after another mass gathering along the border area in which thousands of Palestinians, some burning Israeli flags and torching tires, staged a protest against the ten-year-old blockade. Hamas did not comment.
The army had been monitoring the tunnel system and made a decision to act when the tunnel crossed into Israeli territory, "tens of meters" from the southern Israeli community of Nahal Oz. "That's really how we find a tunnel".
Conricus did not elaborate on the means of detection nor how the tunnel was filled.
Some military sources hypothesized that the recent Hamas-led riots in the area were orchestrated to divert attention from the tunnels, reflecting the terror group's complete military and political control of Gaza.
The laboratory "uses innovative ground research, which includes scanning of cavities and their dynamics, (and) strives to develop new discovery and mapping techniques", a military statement said.
The death brings to 28 the number of protesters killed in two weeks of border protests.
Hamas, which is sworn to Israel's destruction, has denied having any such plans.
Defence Minister Avigdor Lieberman said it was the longest and deepest Gazan tunnel discovered by Israel.
