CONFLICT ENTERS FOURTH DAY: Israel and Iran have begun a new round of attacks, as the conflict between the two heavily armed rivals enters its fourth day.

BEIRUT — Iran and Israel traded air raids and ballistic missile barrages overnight and into the evening Sunday, with neither side showing any inclination to back down from an escalating grudge match between the two longtime enemies.

President Trump rejected an Israeli plan in recent days to kill Iran's Supreme Leader Ayatollah Ali Khamenei, a senior U.S. official told USA TODAY.

The president had opposed Israeli action against Iran but came to believe that Israel had reason to act and that the U.S. would have to lend some support.

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 five killed and dozens more wounded in the fourth day of a conflict between the regional foes that showed no sign of slowing.

An Israeli plan to assassinate Iranian Supreme Leader Ayatollah Ali Khamenei as part of its military offensive targeting the country's nuclear program has been privately vetoed by U.S. President Donald Trump.

President Donald Trump on Sunday issued a stark warning to Iran against retaliating on U.S. targets in the Middle East while also predicting Israel and Iran would “soon” make a deal to end their escalating conflict.
