The IDF has been working to locate infiltration tunnels along Israel's northern border in light of the threat Hezbollah poses on the Jewish state, a recently-retired IDF commander said Saturday. The IDF's former corps commander of the General Staff, Maj.-Gen. Gershon Hacohen told Israel Radio that fighters from the Lebanese-based terror group have been gaining experience from their involvement in the Syrian civil war. He warned that Hezbollah would yield stronger fighters in the organization's next conflict with Israel.
