Border control agents, working in conjunction with the Shin Bet internal security agency, confiscated a large shipment at the Tarkumia Crossing in the Hevron region.
The shipment, bound for Gaza via Israel, carried a large quantity of building materials for rockets and mortars, along with heavy-duty electric motors, used to construct and fortify underground facilities.
Security officials believe the shipment was destined for the Hamas terror organization.
The smuggled materials were concealed in what appeared to be a shipment of textiles and jewelry.
Officials say the shipment included hundreds of special pipes used to manufacture rockets and mortars, in addition to motors Hamas likely intended to use to expand its vast underground network.
The shipment was destined for the Kerem Shalom crossing into Gaza via Israel. Authorities are searching for those responsible for the smuggling attempt.
