We won’t hesitate to act in order to defend our civilians,” said Maj. Gen. Eyal Zamir. Zamir also warned Hamas that such tunnels risk with escalation and are a threat also for the Gaza civilian population. Addressing Hamas operatives, the general added: “I’ve warned the enemy and I’ll warn them again: Anyone who goes into such a tunnel, endangers himself. These terror tunnels are a death trap for you.” The IDF destroyed yesterday the second attack tunnel using an undisclosed new technique that did not include the types of explosives used in the previous one.
