The Israeli military is speeding up construction of its first underground border wall.
The 40-mile-long wall will run the length of Israel's border with the Gaza Strip to counter tunnels that Palestinian militants have dug into Israeli territory.
Dozens of tunnels, reportedly running dozens of miles long, have been constructed in attempts to infiltrate Israeli territory and carry out attacks, according to the Israeli military.
"This is now a significant game changer," said Israeli military spokesman Lt. Col. Jonathan Conricus.
