Regime change in Iran could be a result of Israel's military attacks on the country, Israeli Prime Minister Benjamin Netanyahu told Fox News on Sunday, saying Israel would do whatever is necessary to remove the "existential threat" posed by Tehran.

Israeli strikes have killed at least four senior Islamic Revolutionary Guard Corps commanders, including Hossein Salami.

Iran has long maintained that its nuclear programme is for civilian purposes only. It has several facilities around Iran, at least some of which have been targeted in the Israeli strikes.

The retaliatory strikes came on Saturday, a day after Israel killed top Iranian military leaders and scientists and destroyed an aboveground nuclear enrichment plant near Natanz.

Sirens sounded in Israel as Iran launched dozens of ballistic missiles in retaliation for Israel's strikes on its nuclear facilities.

The targeting of leaders and sensitive sites relied on activating intelligence teams, pre-positioned weapons and other capabilities that had long lain dormant.

Israel launched strikes across Iran on Friday, saying they targeted the "heart" of Iran's nuclear programme. The strikes killed Hossein Salami, chief of Iran's Islamic Revolutionary Guards - a powerful branch of the country's armed forces - other senior military figures and nuclear scientists, Iranian state media reported.
