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.

DUBAI, United Arab Emirates (AP) — Israel launched an expanded assault on Iran on Sunday, with direct strikes targeting its energy industry and Defense Ministry headquarters, while Tehran unleashed a fresh barrage of missiles blamed for the deaths of four people and injuries of many others.

"The full strength and might of the U.S. Armed Forces will come down on you at levels never seen before," Trump warned.

There are reports of injuries after Iranian attacks on Haifa and Tel Aviv overnight, with earlier strikes by Israel on the Iranian capital.

Israel and Iran have opened a new chapter in their long history of conflict. Israel launched a major attack with strikes early Friday that set off explosions in the Iranian capital of Tehran.

Iran conflict could open opportunities for Russia to possibly become a power broker to help end the confrontation.

Israel launched a wave of unprecedented strikes on Iran shortly before sunrise Friday morning, hitting key sites in the nation’s nuclear program.

Anger is mixed with worry as Iranians in the capital of Tehran woke up Saturday to images of their country’s retaliatory attacks on Israel.
