Hello from CNN. I'm Anna Sturla with the five things you need to Know for Monday, November 20th.

'12,700 Palestinians have been killed as a result of Israeli attacks on Gaza since October 7th. That's according to figures from the Palestinian Ministry of Health and the West Bank, which draws its data from Hamas-run health authorities in the strip.

This is what matters. We are witnessing a killing of civilians that is unparalleled and unprecedented in any conflict since I am secretary general.

'That's UN Secretary General Antonio Guterres speaking today. Guterres specifically called out the high number of children killed in Gaza. The PMH has reported more than 5000 of those killed were children. The World Health Organization reported earlier today that 28 out of 33 premature babies that were in Al-Shifa hospital have been evacuated into Egypt. A senior W.H.O. official said three babies were reunited with their families, while two died over the weekend.

A federal appeals court has struck down a key tool used to enforce one of the nation's landmark civil rights laws. The Voting Rights Act bans election rules that discriminate based on race. Today, the eighth U.S. Circuit Court of Appeals ruled that private entities, such as private individuals, can't sue under one of the law's provisions. But the vast majority of cases brought under the act are brought by private plaintiffs. CNN's Joan Biskupic breaks down the big picture.

It's really big. It rejects years and years, decades of precedent. It's setting up a major confrontation for the Supreme Court.

'Elon Musk is continuing to face fallout in the wake of endorsing an anti-Semitic conspiracy theory. Last week, Musk agreed with an anti-Semitic post on his social media platform, X, formerly known as Twitter, that claims Jewish communities promote anti-white racism. Today, the White House joined Threads, a direct competitor to Musk's X. White House press secretary Karine Jean-Pierre said there weren't imminent plans to suspend official White House accounts on X.

We are going to continue, continue to certainly call that out, condemn those types of hateful, hateful comments that could be incredibly dangerous.

'The fallout is embroiling others with a stake in Musk's companies. One Tesla shareholder is calling on the company's board to suspend Musk. Since Musk's comments, at least half a dozen major advertisers like Disney, IBM and NBCUniversal have stopped spending their ad dollars at X. Musk has responded by suing the progressive watchdog group Media Matters today over its report highlighting anti-Semitic and pro-Nazi content on the platform.

'Researchers have diagnosed the first case of Stage 2 CTE in a high school football player. In July 2019, an 18-year-old from Kansas City, Missouri, took his own life, leaving behind a message to his loved ones that he was experiencing a, quote, "living hell inside of my head." According to the Concussion Legacy Foundation, the teen had the worst brain trauma ever seen in someone so young. A director of the Boston University CTE Center, who diagnosed him, said his condition was caused by playing tackle football for about ten years, starting in the third grade. CTE is a disease that affects the brain like Alzheimer's. It's most commonly associated with people who have played American football professionally, and it's linked with a number of traits, including aggression, memory loss, confusion, depression and suicidal behavior.

'Next up, a 23-year-old becomes the youngest college head coach to win a national championship.

Erin Matson is just 23 years old, but she has already won five national championships in field hockey. Four of those were as a player for the University of North Carolina at Chapel Hill. But as of this weekend, she has won yet another, this time as coach. The UNC Tar Heels beat the Northwestern Wildcats 2 to 1 on Sunday, securing the program's 11th national title. And according to NCAA.com, that makes Matson the youngest college head coach to win a national championship.

That's all for now. I'm Anna Sturla. Our next episode drops at 6 a.m. Eastern.
