Israel-Iran updates: Iran launches more missiles at Israel, sirens sound in Tel Aviv and Jerusalem

Israeli Prime Minister Benjamin Netanyahu's office said on Sunday that at least 13 people have been killed since Friday in Israel by Iranian strikes, as Tehran retaliates to Israel's ongoing attacks on Iranian nuclear facilities, military sites and leaders.

Two consecutive nights of Iranian attacks saw around 200 ballistic missiles fired into the country, the prime minister's office said, with 22 places in Israel hit either directly or by falling missile debris.

At least 380 people have been injured, the prime minister's office said, nine seriously.

The Israeli military on Sunday morning issued an "urgent" warning to Iranians near facilities producing weapons.

"Your presence near these facilities puts your life at risk," the Israel Defense Forces said in social media posts in Farsi and Arabic.

The Israeli Air Force said it had intercepted seven drones launched toward Israel with about an hour on Sunday morning.

Iranian aerial strikes targeting Israel killed eight people and injured more than 200 others overnight, Israel's Foreign Ministry said on Sunday morning.

Four of the dead were children, the ministry said in a social media post, which accused Iran of "deliberately targeted Israeli civilians as they slept." Another 35 people were missing, the statement said.

The Israeli Police said there had been "multiple confirmed fatalities" and injuries in the central area of the Tel Aviv District, where a rocket struck.

"Iran targets innocents," the ministry said. "Israel targets nuclear and military sites -- to stop the world's most dangerous terror regime from acquiring the world's most dangerous weapons. We will do whatever it takes to defend our people. Israel is doing what must be done."
