TEL AVIV, Israel, July 25 (UPI) -- The Israel Defense Force, working to destroy underground tunnels between Gaza and Israel, said 31 tunnels have been located since its ground invasion began two weeks ago.
The tunnels -- used to move smuggled goods and medical supplies in addition to weapons and explosives, as well as starting points for military incursions into Israel -- are large and elaborate. Some can accommodate trucks, and are 60 feet underground to avoid discovery.
