Washington: The United States expects an attack by Iran against Israel but one that would not be big enough to draw Washington into war, a US official said late on Thursday.
The White House said earlier Washington did not want conflict to spread in the Middle East and the US had told Iran it was not involved in an air strike against a top Iranian military commander in Damascus.
The White House added it warned Iran to not use that attack as a pretext to escalate further in the region.
Suspected Israeli warplanes bombed Iran's embassy in Damascus on Monday in a strike for which Iran has vowed revenge and in which a top Iranian general and six other Iranian military officers were killed, ratcheting up tension in a region already strained by the Gaza war.
Iranian sources told Reuters Tehran has signalled to Washington that it will respond to Israel's attack on its Syrian embassy in a way that aims to avoid major escalation and it will not act hastily, as Tehran presses demands including a Gaza truce.
The United States has been on high alert about possible retaliatory strikes from Iran and US envoys have been working to lower tensions.
Palestinian Islamist group Hamas attacked Israel on Oct. 7, killing 1,200, according to Israeli tallies. Israel's military assault on Hamas-governed Gaza has since killed over 33,000 according to the local health ministry, displaced nearly all of Gaza's 2.3 million population, caused a humanitarian crisis and led to genocide allegations that Israeli denies.
Iran-backed groups have declared support for Palestinians, waging attacks from Lebanon, Yemen and Iraq. Tehran has avoided direct confrontation with Israel or the United States, while declaring support for its allies
