The world’s leading state-sponsor of terrorism – the Islamic Republic of Iran – is behind Palestinian Islamic Jihad's firing of over 600 rockets at communities in Israel over the weekend, according to top military experts. Brig. Gen. (res.) Amir Avivi, a former deputy commander of the Israel Defense Forces’ Gaza Division, told Fox News Digital that there is "more than a slight possibility that Iran ordered [PIJ attacks] or it was supported by Iran." Israel launched a preemptive mission—Operation Breaking Dawn—on Friday to stop "PIJ from firing anti-tank missiles from northern Gaza into Israel," said Avivi.
