The Israeli Air Force has so far attacked nine air defence and radar systems as well as a petrochemical complex in Iran, according to military sources, after fighting between the two sides flared up again overnight.
According to the military, Iran used the petrochemical site to manufacture materials for making missiles.
Iran, meanwhile, fired more than 20 ballistic missiles at Israel since Sunday evening, the sources said on Monday.
Iran fired rockets at Israel on Sunday evening and Israel retaliated with airstrikes against Iran on Monday, in what were the first mutual attacks since a ceasefire negotiated between Iran and the US took effect in April.
The Israeli military is prepared for a longer war, the sources said, shortly before Iran announced that its attacks on Israeli were over.
