President Donald Trump rejected an Israeli plan in recent days to kill Iran's Supreme Leader Ayatollah Ali Khamenei, two U.S. officials told ABC News. The officials stated that Israel shared with the United States that they had a window to kill Iran's leader but the president was not on board with the plan.

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.

The conflict, the most intense fighting between the two countries in decades, has been met in the United States with feelings of “frustration and helplessness,” as well as heartbreak.

Israelis have been rallying around the flag since the attacks began last week, even if not around Netanyahu himself.

It’s too soon to tell how exactly the current wave of Israeli strikes could transform the region, but one thing is clear: Israel’s actions have fundamentally reshaped the security landscape of the Middle East.

The United States is shifting military resources in the Middle East in response to Israel’s strikes on Iran and a possible retaliatory attack by Tehran.

Israel launched an expanded assault on Iran on Sunday, targeting its energy industry and Defense Ministry headquarters, while Tehran unleashed a deadly barrage of missiles.
