Biden says he does not know if Iran will stand down on response threats

US President Joe Biden expressed hope Iran would stand down despite its threat to avenge the assassination of Hamas’ leader Ismail Haniyeh in Tehran and Hezbollah commander Fuad Shukr, as fears mounted that the Islamic Republic would launch a direct attack against the Jewish state.
Asked by reporters whether Iran would stand down, Biden said on Saturday in response to a shouted question, "I hope so. I don't know.”
