Israel and Iran exchange missile attacks for a third day; nuclear sites hit, death tolls rise, airspace shut, U.S. warns Tehran against retaliation.

Israel had a plan to assassinate Iranian Supreme Leader Ayatollah Ali Khamenei, but President Trump vetoed the operation, according to reports.

DUBAI — Israel unleashed airstrikes across Iran for a third day Sunday and threatened even greater force as some Iranian missiles evaded Israeli air defenses to strike buildings in the heart of the country. Planned talks on Iran’s nuclear program, which could provide an offramp, were canceled.

Explosions have been seen over Tel Aviv and Jerusalem as the country faces yet another barrage of missiles from Iran. It comes after explosions were reported in central Tehran, as attacks continue between Iran and Israel.

Almost 48 hours after the eruption of hostilities between Israel and Iran, concerted but limited diplomatic efforts appear to be underway to prevent the conflict from spiraling out of control and ultimately bring it to a resolution.

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.

Israel warns "Tehran will burn" if Iran continues firing missiles, while state media say 60 people have been killed in a strike on Iran's capital.
