Israel’s attack on Iran was long in the making – the result of years of meticulous planning by Israel and days of high-stakes talks between Tel Aviv and Washington, officials told CNN.

Israel's Prime Minister Benjamin Netanyahu says his country will strike "every site and every target of the ayatollah regime" in Iran.

Iran will continue its military operations until Israel regrets its actions, the spokesperson for Iran's Armed Forces General Staff, Brigadier General Abolfazl Shekarchi, said on Saturday. Speaking to Iranian state television, Shekarchi commented on Israel's recent attack against Iran and Tehran's subsequent response.

The United States has said that it is not involved in Israel's strikes on Iran and that it's priority is the safety of US personnel in the region.

The IDF says Iran has launched about 100 drones towards its territory and says it killed Revolutionary Guards commander Hossein Salami in overnight 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.

According to Iranian media, around 60 people, including 20 children, had been killed in an attack on a housing complex. At least three people were killed and several others were injured on the Israeli side as waves of missiles streaked across the Jerusalem sky.

The strikes are a sign of Israel’s shift away from restraint, containment and short wars, and toward using force to project power across the Middle East.
