Israel unleashed airstrikes across Iran for a third day and threatened even greater force as some Iranian missiles evaded Israeli air defenses to strike buildings in the heart of the country.

The Israeli military struck "over 170 targets" in Iran in three days, the Israel Defense Forces (IDF) said on Sunday.

At least ten people were killed in Israel overnight, after multiple Iranian missiles evaded the country's advanced defense systems. Explosions rocked Tehran, but casualties weren't immediately clear.

Israel’s sweeping attack across Iran struck at the heart of Tehran’s nuclear program, delivering a blow to the country’s ability to enrich uranium and potentially setting its nuclear ambitions back by months or years.

Israel has said it launched Operation Rising Lion to deal a blow to Iran’s nuclear ambitions. Prime Minister Benjamin Netanyahu has claimed that the strikes are essential to ‘roll back the Iranian threat to Israel’s very survival’ and that Tehran could build a nuclear weapon within a few months.

U.S. military leaders and elected officials are grappling with a worsening diplomatic and security crisis in the Middle East.

Three people have been killed in Israel, according to officials and local media, with both sides saying the strikes will continue.
