An Israeli research center said North Korea exported technology on digging a network of regional tunnels extending tens of kilometers to Lebanese Shiite militant group Hezbollah. 

According to a report released by the Alma Research and Education Center on Tuesday,  Hezbollah launched a project forming what the report called a “land of tunnels” with the help of the North and Iran after the Second Lebanon War in 2006.  

The report said in 2014, Hezbollah signed a 13 million dollar-deal with the North’s Korea Mining Development Trading Corporation(KOMID) for the supply of materials to excavate tunnels on the border and for the transfer of North Korean technology to Hezbollah.   

The report said that in line with the deal, KOMID sent six of its personnel to southern Lebanon to assist and to support the construction of underground missile storage sites and missile launch pads.  

The report also said that as of 2014, about six million dollars was transferred to the North Korean company from Lebanese and Iranian officials in China and Thailand, in the form of heroin and cocaine meant for distribution in East Asian markets.

The report cited that Hezbollah's model of the inter-regional tunnels is the same as the North Korean model, saying that through such tunnels, hundreds of armed soldiers can move rapidly and undetected underground.
