After Palestinian terrorists fired around 20 rockets at Israel on Sunday evening, Israel’s Iron Dome system leapt into action.

Just hours after a Palestinian who tried to plant a bomb next to the Israel-Gaza security barrier was shot dead in his tracks, terrorists launched a barrage of more than 20 rockets at southern Israel.

While none of the terror groups in Gaza immediately claimed responsibility for the attack, Palestinian Islamic Jihad operatives appeared to be the most likely culprits.

After air raid sirens rang out in southern Israel, the Iron Dome anti-missile defense system was activated, downing 13 of the Palestinian rockets.
