Iran launched dozens of ballistic missiles toward Israel on Friday night in retaliation for Israel's surprise attack early Friday. Israel struck at the heart of the Iran's nuclear program, killing several nuclear scientists as well as high-ranking military leaders, according to Israeli officials.

The strikes came after the Israeli military said it had carried out fresh strikes on Iran nuclear infrastructure sites.

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

Israel’s ongoing attacks on Iranian nuclear sites, generals, and scientists killed 78 people and wounded more than 320 on Friday, Iran’s ambassador told the U.N. Security Council, but he said “the overwhelming majority” of victims were civilians. Israel described the new wave of hostilities as the beginning of “Operation Rising Lion.”

Tehran said American bases in the Middle East could face reprisals if the U.S. helped repel Iranian attacks on Israel.
