Israel said on Sunday it destroyed a guerrilla tunnel from the Gaza Strip and gave rare details on a classified military laboratory spearheading efforts to foil the cross-border digs.
Palestinian gunmen used tunnels to blindside Israeli forces during the 2014 Gaza war. 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.
It is the fifth such detection in as many months and Israeli officials regard publicity around their tunnel hunts as a double-edged sword.
