Hundreds of civilians, mostly in Iran, have been killed by dueling airstrikes despite international pleas for de-escalation.

PresidentTrump urged Iran to reach a deal with Washington on its nuclear program, warning that Israel’s attacks “will only get worse.”

Iran fired a new wave of missile attacks at Israel early Monday, killing at least eight people, while Israel warned hundreds of thousands of people in the middle of Tehran to evacuate ahead of new strikes.

A dramatic spike in the potential for all-out war between Israel and Iran would typically be expected to spark an immediate and strong rally in the U.S. dollar, with investors seeking the safety and liquidity of the world's reserve currency.

Israel said on Monday that it had struck the command center of Iran’s elite Quds Force, as the fiercest and deadliest confrontation in the history of the Israeli-Iranian conflict entered its fourth day.
