Iran gave no warning to US over attack, US officials say

US State Department spokesperson Matthew Miller said Iran gave no warning of its attack on Israel.

"We had no warning from the government of Iran that they were going to launch such an attack," Miller said, adding it is "absolutely false".

The Pentagon also denied receiving a warning. 

Miller added that the US is not aware of “any civilian casualties” inside Israel or damage to US facilities in the region, following Iran’s attack on Israel.

Miller said the US was investigating reports of a Palestinian civilian killed in the occupied West Bank during the attack. 

Miller also reiterated US condemnation of Iran's attack, saying it was a “state-on-state attack to defend” groups the US considers terror organisations. 

Asked whether Israel sought to escalate fighting in the region, Miller said: “We have seen Israel expand the nature of its attacks on Hezbollah" but that was different than Iran's attack.
