An Israeli security officer at the Erez Crossing between Gaza and Israel seized and confiscated a large number of mailbags filled with packages containing weapons, communications and scuba-diving equipment that was being smuggled into Gaza, according to a report in Israel’s Ma’ariv daily on Thursday.

Of 250 mailbags set to be transported by Israel’s Coordinator of Government Activities in the Territories (COGAT)—the unit in the Israeli Defense Ministry responsible for implementing Israeli government policy in the Area C of the West Bank and vis-à-vis the Gaza Strip—172 were deemed to contain “suspected dual-use products.”

Those items were a collection of electronic and military equipment that could potentially be used for to carry out terrorist attacks.

They included weapon sights, scanners, hidden cameras, diving lights, military boots, digital microscopes, weapons holsters and more.
