Why world leaders fear an escalation of Israel-Gaza war

The Israel-Gaza war has caused reverberations around the world and diplomatic efforts are intensifying to stop the conflict from escalating. Iran has warned Israel that the Middle East could spiral out of control if it does not stop strikes on Gaza. It says the US is also "to blame" for providing military support to Israel. Top US officials are warning the conflict could spread. US Secretary of State Antony Blinken has talked about a "likelihood of escalation" from Iranian proxies, such as Hezbollah or Hamas, and said the US was "taking every measure" to ensure it can defend" Israelis and US citizens. How high is the risk of the conflict escalating across the region? What are countries doing to prevent an escalation? Is there a real danger of a general war in the Middle East that could pull in Iran, the US and even Saudi Arabia?
