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 and Iran traded fire for a third straight day on Sunday, with rising casualties and expanding targets marking a sharp escalation in the conflict between the longtime adversaries.

Foreign Minister Abbas Araghchi says US President Donald Trump publicly and explicitly confirmed he knew about attacks.

President Donald Trump said early on Sunday that if Iran attacks the United States in any way, it would face the might of the US military “at levels never seen before.”

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 United States is the main international backer of Israel, Iran's biggest regional foe. It is also a close ally of Sunni Gulf monarchies which for years pursued their own rivalry with the Islamic Republic, seeing it as their main regional threat.

Experts suggest the U.S. has a strategic opportunity to leverage Iran's weakened position for a nuclear deal after Israel's targeted strikes on Iranian nuclear and military sites.

The death toll grew Sunday as Israel and Iran exchanged missile attacks for a third consecutive day, with Israel warning that worse is to come.
