AMNA NAWAZ: In the day's other headlines: U.S.

and Canadian officials are expressing confidence they can reach a final trade deal after President Trump paused tariffs on some Canadian goods.

MAN: I am very confident in these discussions.

AMNA NAWAZ: Canada's minister for U.S.

trade joined Trade Representative Jamieson Greer for talks in Washington today.

The tariffs were supposed to take effect after midnight last night, but just before the deadline, President Trump said on social media he was pausing the 50 percent tariffs for a three-day period.

Speaking to reporters at the site of a new White House helipad today, Trump implied that the deal is nearly done, calling it -- quote -- "very fair."

DONALD TRUMP, President of the United States: It's good for everybody.

But our farmers are going to be thrilled.

Our manufacturers are going to be thrilled.

And, basically, we have no tariffs going into Canada anymore.

Canada was charging us tremendous tariffs.

We no longer have any tariffs.

AMNA NAWAZ: For his part, Prime Minister Mark Carney congratulated the negotiations and said the two sides are -- quote - - "moving towards an agreement."

The Israeli military is opening criminal investigations into two high-profile killings by its troops in Gaza.

The deaths of 5-year-old Hind Rajab and her family in 2024, as well as the fatal shooting of 15 Palestinian medical workers the following year, caused international outrage.

The cases were among 150 incidents reviewed by the military.

In the meantime, local Palestinian officials say at least 10 people were killed in two strikes in Gaza today.

Israel says it was targeting Hamas commanders.

A relative of one of those killed today called for an end to such attacks.

MOHAMMED AL-TIMSAH, Displaced Palestinian (through translator): Every day, they announce a cease-fire.

There is no cease-fire.

We are exhausted.

Every day is always worse than the day before.

Women, elderly, children, they have become scattered body parts.

End this misery for us.

AMNA NAWAZ: Following today's strikes, a Hamas official accused the U.S.-backed Board of Peace as providing, as he put it, cover for Israeli attacks.

The board was formally established earlier this year to oversee the cease-fire and reconstruction of Gaza and other conflicts.

The United Arab Emirates says it's halting all trade with Iran a day after it accused Tehran of launching missiles toward its territory.

The action further isolates the Islamic Republic, which is currently suffering under U.S.

sanctions and a blockade.

Iran denies the attack.

In the meantime, Iranian Parliament Speaker Mohammad Bagher Ghalibaf arrived in Iraq today for a three-day visit as Iraq seeks special status for its oil exports through the Strait of Hormuz.

The country relies on oil for about 90 percent of its budget, with most exports normally passing through the strait.

Ukraine's President Volodymyr Zelenskyy fired one of his most senior officials today amid a corruption investigation.

The dismissal of Iryna Mudra as deputy head of the office of the president is just the latest political challenge for Zelenskyy, though he is not implicated in the probe.

It comes a day after Ukraine's recently fired Defense Minister Mykhailo Fedorov called for national elections in a direct challenge to Zelenskyy.

He's the popular architect of Ukraine's long-range drone campaign targeting Russian energy sites and warehouses.

President Vladimir Putin tried to downplay the impact of those strikes today.

VLADIMIR PUTIN, Russian President (through translator): Of course, such attacks have no critical consequences.

They never have and never will.

But they certainly cause us harm.

That much is obvious.

We understand this.

We see it.

And we know it.

AMNA NAWAZ: Meantime, in the southern Ukrainian region of Kherson, local officials say a Russian drone tore a hole through the roof of this bus, killing at least four people.

President Zelenskyy called the attack vicious.

Russia has long denied targeting civilians.

NASA has released images showing a crater on the moon caused by the crash earlier this month of a SpaceX rocket.

This is how the lunar surface looked before impact.

Here you can see the 60-foot crater caused when the upper stage of the Falcon 9 rocket plowed into the moon at more than 5,000 miles an hour.

The rocket was originally launched in 2025, and its defunct portion then drifted into space for more than a year.

NASA has said the crash posed no danger to humans, but it's raised concerns about other space debris.

Also today, NASA said it's dropping plans to try to rescue its aging Swift space telescope.

Officials had launched a mission to try to boost it into higher orbit, but instead, the observatory will likely burn up on reentry later this year.

Pharmaceutical giants Moderna and Merck said today that their experimental cancer treatment showed signs of success in a study with high-risk melanoma patients.

The first-of-its-kind treatment involves an mRNA vaccine that's tailored to individual patients and pairs it with a separate immunotherapy drug, Keytruda.

The combination was effective in helping prevent the skin cancer from returning or spreading.

The treatment still needs regulatory approval, and the companies have only provided broad outlines of their findings.

But Moderna stock surged on the news, jumping nearly 177 percent.

Elsewhere on Wall Street today, stocks regained some ground after the Treasury Department moved to ease pressure on the bond market.

The Treasury also said today that the federal debt topped $40 trillion for the first time ever.

By the close, the Dow Jones industrial average was up more than 100 points.

The Nasdaq managed a small gain of around 40 points.

The S&P 500 also ended slightly higher.
