AMNA NAWAZ: We start the day's other headlines in Washington state, where authorities say there's no hope of finding any more survivors from yesterday's implosion at a paper mill near the Oregon border.

GOV.

BOB FERGUSON (D-WA): We're bracing ourselves for this being the deadliest industrial tragedy in modern Washington state history.

AMNA NAWAZ: Officials say two people are now confirmed dead after a tank imploded at the Nippon Dynawave Packaging facility and released a harmful chemical mixture called white liquor.

Nine others remain missing and are presumed dead.

Another eight people were injured, including a firefighter.

Officials said today that some of the contamination entered the local Columbia River, but stressed that there's no risk to the local water supply.

Peace talks between the U.S.

and Iran remain in flux, even as Iranian state TV outlined an unofficial framework agreement earlier today.

It would restore commercial shipping in the Strait of Hormuz to prewar levels, while the U.S.

would withdraw its forces and lift a naval blockade.

The White House called the report a -- quote -- "complete fabrication."

Meantime President Trump convened his Cabinet at the White House, where he said domestic political pressures like the midterms would not affect his war strategy.

DONALD TRUMP, President of the United States: Iran is very much intent, they want very much to make a deal.

So far, they haven't gotten there.

We're not satisfied with it.

But we will be.

We will be.

Either that, or we will have to just finish the job.

They're negotiating on fumes.

But we will see what happens.

Maybe we have to go back and finish it.

Maybe we don't.

AMNA NAWAZ: Separately today, Israel warned residents across Southern Lebanon to leave, signaling an expansion of its campaign against Hezbollah militants there.

It's the first such warning since an uneasy cease-fire went into effect last month.

Yesterday, several Israeli strikes came down near the Qaraoun Dam, which sits on the largest water reservoir in Lebanon.

Also today, Hamas confirmed that Israeli airstrikes killed their latest military leader in Gaza.

Mourners and Hamas supporters carried the body of Mohammed Odeh along with some of his family members through the streets of Gaza City.

It comes less than two weeks after Israel's killed Odeh's predecessor, Izz al-Din al-Haddad.

The strikes also injured at least 12 others and came on the eve of the Muslim holiday of Eid al-Adha.

It left residents sifting through rubble for their belongings or other bodies.

MOHAMED ISHTEIWI, Gaza City Resident (through translator): This is a day of Eid.

It is a holy day, and some people forgot about the war.

But after what happened, people were shocked completely.

They couldn't take it anymore.

AMNA NAWAZ: The attacks targeting Odeh last night came despite a cease-fire between Israel and Hamas that's been in effect since October.

Gaza health authorities say such strikes have killed nearly 900 Palestinians since the truce took effect.

Uganda is closing its border with the Democratic Republic of Congo -- quote -- "with immediate effect," as authorities try to slow the spread of Ebola.

There are now nearly 1,000 suspected cases in the DRC and at least 220 suspected deaths.

In the meantime, the World Health Organization has started construction on a treatment facility in the east of the country.

And the Trump administration is reportedly planning to send Americans exposed to Ebola to a new facility in Kenya, instead of flying them back to the U.S., though that site has not yet been built.

In Laos, five people who were trapped in a flooded cave for more than a week have been found alive.

Rescuers celebrated outside the cave when contact was made with the missing villagers.

Inside, video showed the men, lit by flashlights, huddled together smiling and safe.

They entered the cave on May 19, with some reports saying they were searching for gold.

Heavy rains triggered flash flooding that blocked their exit.

Lao and Thai rescuers are continuing to search for two others who remain missing.

On the South Lawn of the White House, construction is under way for an octagon-shaped cage to host next month's UFC bout.

A giant arch is already looming over the historic mansion.

The mixed martial arts event is part of celebrations to mark 250 years of American independence and is scheduled for June 14, both Flag Day and President Trump's birthday.

He's been a longtime supporter of the UFC, or Ultimate Fighting Championship, and was the first sitting president to attend a fight.

When finished, the temporary arena is expected to hold 5,000 people, as seen in this rendering.

On Wall Street today, all three major indices closed at all-time highs as oil prices eased.

The Dow Jones industrial average added nearly 200 points on the day.

The Nasdaq rose just 18 points, so a small gain there.

The S&P 500 added just one point, but technically enough for a new record.

And Ferrari is now taking orders for its new first-ever electric vehicle.

But if critics and financial markets are any indication, interest in the new car may be low.

The launch of the Luce, meaning Light in Italian, landed with a thud among Ferrari fans, who bristled at its bubble-like exterior.

A former company chairman warned of -- quote -- "the destruction of a legend," and the company stock initially fell in Milan and on Wall Street.

But Pope Leo seemed impressed when he was given a firsthand look outside his summer residence yesterday.

The Luce comes with 1,000 horsepower, a 10-inch touch screen, and an estimated price tag of more than $600,000.
