Israeli soldiers hadn’t even finished their dinner when they heard a “crazy boom” at their training base in northern Israel.

“The iron door bent. We didn’t know what happened, and suddenly something pierced through the ceiling. We didn’t hear anything before, just the huge blast. No sirens went off,” a soldier inside the Golani Brigade training base told Ynet news.

The boom was caused by a Hezbollah-launched drone that evaded Israeli fighter jets and struck the base in Binyamina, just south of Haifa. Four soldiers were killed in the attack, with 60 more injured.
