The casualties were reported to include a top Iranian intelligence officer.
Iran has thus far avoided direct participation in Israel's war against Hamas, but multiple Iranian-backed militias - including Hamas, Hezbollah, the Houthis, and factions in Iraq - have stepped up attacks against Israel and Israel-affiliated targets since the war began.
The withdrawal forms the latest of a series of events that indicate growing chances of a large-scale regional conflict, including the increased Iranian-backed attacks, multiple nations dispatching warships to the Red Sea, and reports that US President Joe Biden is planning a drastic response to the killing of three US soldiers in a drone strike that could span multiple countries.
Despite this, several powers have declared their desire to avoid such a a conflict to any possible degree, including both Israel and the USA.
