Live from NPR News in Washington, I'm Janine Herbst. The UN's top humanitarian official says the U.S. and Israeli war with Iran is costing about a billion dollars a day.

This at a time when countries are scaling back humanitarian assistance. And he says he's worried about the fallout of this latest conflict, as MPRs Michelle Kellerman reports.

President Trump says there will be no deal with Iran, but only in his words, unconditional

surrender. And he says in the aftermath, partners and allies will bring Iran back from the brink.

The UN's humanitarian chief, Tom Fletcher, is calling for de-escalation now, saying he's worried about the knock-on effects.

War doesn't stay neatly within borders or on desktop military plans.

It tears through markets, supply chains, food prices.

And he says when that happens, the world's most vulnerable people tend to suffer the consequences.

And a new NPR PBS News, Marist poll is out today, revealing a majority of Americans are against military action in Iran.

Empires Domenico Montanaro has more. Fifty-six percent of the almost

1,600 people interviewed say they oppose military action in Iran. And a similar number,

55 percent say they believe Iran only presents a minor threat or no threat at all to the United

States. President Trump only gets a 36 percent approval rating for his handling of the war.

Democrats and independents are largely aligned in opposition to the military action

in disapproving of Trump's handling and in viewing Iran as not a major threat.

But Republicans continue to heavily support the president with 8 and 10 supporting the military

action and Trump's handling

of it. Domenico Montanaro and PR News, Washington.
