Israel and Iran bombarded each other for a third day, with international concern growing that the conflict will spread across one of the world’s key oil-producing regions.

The death toll is rising as Israel and Iran traded missile strikes for a third straight day. Israel on Sunday hit targets in Tehran, including the Defense Ministry and sites it claims are tied to Iran’s nuclear program.

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

Iran-aligned Iraqi armed group Kataib Hezbollah warned on Sunday it would resume attacks on U.S. troops in the region if the United States intervenes in the conflict between Israel and Iran.

The push to do a deal on the country’s nuclear program could be revived, even after the Israeli strikes scuppered the latest round of talks.

Israel's airstrikes have deepened a climate of fear within Iran, where there is a shortage of reliable information. A woman in Tehran said one of the worst things about the attacks is that they usually come without warning.

U.S. President Donald Trump warned on Sunday that any attack against the U.S. will be met with the "full strength and might" of the U.S. military.
