Israel has recently thwarted dozens of attempts by terrorist groups in the Hamas-ruled Gaza Strip to smuggle in drone components and other weapons parts through the mail.
According to the Israeli Defense Ministry, the items have been discovered during mail inspections conducted by the Crossing Authority at the Erez border crossing.
A collaborative effort by a number of Israeli security and law enforcement bodies is putting pressure on Gaza terrorist groups, forcing them to try to find new smuggling methods. In recent weeks, it appears terrorist groups have turned to the postal service Israel provides to Gaza.
During Operation Protective Edge in the summer of 2014, the Israeli military intercepted a Hamas drone over the coastal city of Ashdod.
