Iran is using cluster bombs against Israel: What are these bombs and why are they banned in war?

Israel has accused Iran of deploying a missile armed with cluster munitions during the ongoing conflict, marking the first reported use of such weapons. These munitions release submunitions over a wide area, increasing the risk of civilian casualties and long-term danger from unexploded ordnance. The use of cluster munitions is banned by over 120 countries, raising humanitarian concerns.
