Iran uses ‘dancing missile’ Sejjil against US-Israel: What makes it different?

The Iran, Israel and the United States conflict has entered its third week, with both sides also taking verbal shots at each other. The US and Israel struck Tehran on the first day, killing Ayatollah Ali Khamenei. His son, Mojtaba Khamenei, was then named the Supreme Leader. However, he has not made any public appearances, with reports suggesting that he was grievously injured in the same attack that killed his father.
