Iran says it has launched waves of ballistic missiles towards Israel in retaliation for a major deadly attack on Tehran’s nuclear sites and military leaders.

Iran fired a new wave of missile attacks on Israel early Monday, triggering air raid sirens across the country as emergency services reported at least three killed and dozens more wounded in the fourth day of open warfare between the regional foes that showed no sign of slowing.

Israel faced retaliation from Iran after launching missiles against Tehran's leadership and energy infrastructure as part of "Operation Rising Lion" this weekend. Iran's military responded with a wave of missile strikes against Israel,

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.”

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