GEOFF BENNETT: The day's other# headlines begin in Toronto,## where a Delta Air Lines plane crashed# while landing at Pearson International## Airport.

Footage from the scene shows the# plane upside down on the snowy tarmac.

The FAA confirms all 80 people who were on board# flight 4819 from Minneapolis were evacuated.

At## least 19 people were injured.

Three of them# are in critical condition.

A temporary ground## stop was put in place at the airport, though# service has since resumed.

It's at least the## fourth major aviation incident across# North America in just the past month.

Officials now say at least 12 people have# died from severe storms that swept through## the South this weekend.

One person died in# Georgia from an uprooted tree that crashed## into a home.

And unrelenting rain that submerged# entire communities killed at least 11 more across## Kentucky.

Floodwaters also submerged parts# of West Virginia, Georgia and Tennessee.

Kentucky's Governor Andy Beshear said that# at least 1,000 people stranded by high waters## had to be rescued.

And he stressed that the# full toll of the storm is still not known.

GOV.

ANDY BESHEAR (D-KY): We are still# in the search-and-rescue phase of this## emergency.

We are still -- we still# have multiple different missions that## are under way.

There are still# people that are in harm's way.

GEOFF BENNETT: Farther west, the 10th and coldest# polar vortex of this season is descending onto## the Rockies and Northern Plains, bringing# what forecasters call life-threatening cold.

In parts of North Dakota, temperatures are# expected to plunge to 50 degrees below zero## when factoring in windchill.

Northern Texas could# feel as low as zero degrees starting tomorrow.

In the Middle East, the Israeli military says a# drone strike killed the head of Hamas' military## operations in Lebanon today.

The attack comes# on the eve of an already extended deadline for## Israel's withdrawal from the country under the# terms of November's cease-fire deal between Israel## and Hezbollah.

An Israeli official now says that# forces will remain across five strategic locations## beyond tomorrow's deadline.

Hezbollah's leaders# said they have no justification in doing so.

NAIM KASSEM, Hezbollah Secretary General# (through translator): On February 18,## Israel must withdraw from all Lebanese# territories which it occupied.. aggression.

If the Israeli army stayed in# a certain location, this means that it is## occupying the location where it remains# after it did not implement the agreement.

GEOFF BENNETT: Meantime, families of Israeli# hostages marched to the Knesset in Jerusalem## today to mark 500 days since their loved ones# were taken in the October 7 Hamas attacks.

Some## 70 Israeli hostages remain in captivity in Gaza.# Of those, around half are believed to be dead.

And more than 48,000 Palestinians have now# been killed in Gaza since Israel launched## its air and ground war there.

That's# according to Gaza's Health Ministry.

In Rome, doctors are now treating Pope Francis# for what they say is a polymicrobial respiratory## tract infection three days after the pontiff was# admitted to the hospital with bronchitis.

In a## statement, the Vatican said the infection# presents a complex clinical picture that## will require an appropriate treatment hospital# stay.

They did not say how long that could be.

All weekend, well-wishers laid flowers# outside the Gemelli Hospital, where Pope## Francis is being treated.

The 88-year-old# has a long history of health problems,## though the Vatican says he# remains in good spirits.

And on this Presidents' Day, a rare artifact# from the nation's first commander in chief is## being put up for sale.

The letter from George# Washington to a subordinate is dated May 7,## 1777, when he was leader of the Continental Army.

Written across both sides# of a single piece of paper,## Washington addresses a recent British raid on a# military supply depot in Danbury, Connecticut.## He writes that the attack could actually# help inspire the American people to arms.## The asking price for this# piece of history, $150,000.
