Israel's military says Iran has fired about 100 drones towards its territory, after Israel launched a major attack on Iran overnight.

The IDF says it carried out strikes on nuclear sites in Iran and says Revolutionary Guard chief Hossein Salami and other commanders have been killed.

Iranian state TV said residential areas in Tehran were hit and civilians were among those killed - including children - though this could not be independently verified.

The attack is part of Operation Rising Lion, Israel's PM says, adding Iran was a threat to "Israel's very survival".

Iran's supreme leader says he won't let Tel Aviv go unpunished.

Israel has declared a state of emergency, saying the country expected counter-attacks "in the immediate future".

Iran has accused the US of supporting Israel's attack, which the US strongly denies.

President Trump said he was aware of the strikes beforehand but emphasised the US played no part.
