AMNA NAWAZ: We start the day's other headlines at the Supreme Court, which is taking up a challenge to Colorado's ban on conversion therapies for LGBTQ+ children.

At issue is whether the Colorado law violates the free speech protections of counselors engaged in the controversial practice.

The justices have already heard arguments in a Tennessee case that examined the legality of state bans on treating transgender minors.

Also today, the court turned down a Republican attempt to block five Democratic-led states from suing oil companies for allegedly hiding the impact of fossil fuels on climate change.

In the North Sea, a cargo ship collided with an oil tanker carrying jet fuel for the U.S. military.

The tanker was anchored off the northeastern coast of England near the Port of Grimsby when it was struck this morning.

The collision triggered multiple explosions, with fuel pouring into the North Sea.

A major rescue operation ensued.

The container ship's owner says one crew member is still missing.

According to local officials, all 36 others across both vessels are safe and accounted for, with one hospitalized.

An investigation into what caused the crash is now under way.

Ukrainian officials tell the Associated Press that a delegation will propose a limited cease-fire with Russia in talks with top U.S. diplomats tomorrow.

He met with Saudi Arabia's crown prince this evening, but is not expected to join personally in tomorrow's talks with the U.S.

In Syria, the interim government has reached a breakthrough deal with the Kurdish-led Syrian Democratic Forces, or SDF.

The group is backed by the U.S. and controls the country's Northeast.

Today's agreement brings most of Syria under government's control.

It also includes a cease-fire and the integration of the SDF into the Syrian army.

Also today, the government announced that a military operation against loyalists of ousted leader Bashar al-Assad has ended.

Last week, gunmen opened fire on a police patrol, which led to some of Syria's worst fighting since the end of the civil war.

Incoming Canadian Prime Minister Mark Carney is promising a quick transition as he is set to succeed just in Trudeau in the coming days.

He's then expected to trigger an election in the days or weeks ahead.

Carney won his party's leadership vote in a landslide this weekend.

The former Goldman Sachs executive and Central Bank governor has already taken a tough line against President Donald Trump's tariff plans.

Carney said he will keep Canada's retaliatory tariffs in place until -- quote -- "Americans show us respect."

MARK CARNEY, Incoming Canadian Prime Minister: We didn't ask for this fight.

We didn't ask for this fight.

The Canadians are always ready when someone else drops the gloves.

MARK CARNEY: So the Americans, they should make no mistake.

In trade, as in hockey, Canada will win.

AMNA NAWAZ: Carney went on to call these -- quote -- "dark days brought on by a country we can no longer trust."

Trump has postponed his planned 25 percent tariffs on many goods from both Canada and Mexico until next month.

In Rome, doctors say that Pope Francis is no longer in imminent danger, but they aim to keep the 88-year-old pontiff in the hospital for several more days due to, they say, the -- quote -- "complexity of the clinical picture and the important infectious picture presented on admission."

Pope Francis entered Gemelli Hospital more than three weeks ago, where he's been treated for double pneumonia.

Doctors say Pope Francis has been receiving supplemental oxygen, but has been able to follow a weeklong spiritual retreat at the Vatican via videoconference.

In Washington, D.C., workers began removing Black Lives Matter Plaza today.

The giant yellow letters were installed in June of 2020 after days of protests there over police brutality in the wake of George Floyd's murder.

D.C. Mayor Muriel Bowser, a Democrat, ordered the renaming of the intersection as an act of defiance during President Trump's first term.

Last week, she announced the removal of the plaza amid pressure from Republicans in Congress.

The work is expected to take about six weeks.

The yellow letters will be replaced by an unspecified set of city-sponsored murals.

Elon Musk is blaming a massive cyberattack for a series of outages that affected his social media platform, X, today.

Writing on social media, Musk said -- quote - - "We get attacked every day, but this was done with a lot of resources.

Either a large coordinated group and or a country is involved."

Experts say it's not possible to verify Musk's claims of cyberattack without seeing technical data from the company.
