The cellphone video is vivid. A Border Patrol agent aims his gun at an unarmed 15-year-old some 60 feet away, across the border with Mexico, and shoots him dead.

On Tuesday, the U.S. Supreme Court hears arguments in a case testing whether the family of the dead boy can sue the agent for damages in the U.S.

Between 2005 and 2013, there were 42 such cross-border shootings, a dramatic increase over earlier times.

Transitioning to adulthood isn't new, but there is a more modern way to describe it: adulting.

Get your car's oil changed? That's adulting. Cook dinner instead of order takeout? That's adulting.

And now a new school in Maine, called the Adulting School, is dedicated to teaching skills like these to fledgling adults so they can become successful grown-ups.

Vitaly Ivanovich Churkin, a veteran diplomat who represented the former Soviet Union and Russian Federation for more than 40 years, died Monday while at work in the Permanent Mission of the Russian Federation to the United Nations. He would have been 65 today.

The Russian U.N. mission said Churkin's death was a "shock," but offered no cause. The New York Police Department said there were no indications of foul play.

Welcome to the bat cave. No, we're not talking about the secret headquarters of a superhero.

This is Gomantong — an ancient cave carved out of 20 million-year-old limestone in the middle of the Borneo rain forest in Malaysia. It's part of a vast network of tunnels and caverns. And it's the perfect hideout for bats.

Up at the top are millions of bats. Literally millions. They hang upside down all day long from the cave's ceiling, sleeping and pooping.

In June 2010, 15-year-old Sergio Hernandez and his friends were playing chicken at the U.S.-Mexico border, daring each other to run up and touch the tall border fence separating Juarez, Mexico, from El Paso, Texas.

At some point during their game, U.S. border patrol agent Jesus Mesa arrived on a bicycle. He detained one of the kids on the U.S. side while the others ran away. Hernandez hid behind a pillar beneath a bridge on the Mexican side of the border. A cellphone video shows the boy peeking out from behind the column, before Mesa shoots and kills him.

President Trump has announced that Army Lt. Gen. H.R. McMaster will be his new national security adviser. McMaster will replace retired Army Lt. Gen.

President Robert Mugabe turns 93 on Tuesday, making him the oldest president in Africa — and the world. He's the only leader most Zimbabweans have ever known, spending nearly 37 years at the helm since independence from Britain and the end of white minority rule in Rhodesia in April 1980.

On Sunday, former Uber engineer Susan Fowler Rigetti published a post on her blog entitled "Reflecting On One Very, Very Strange Year At Uber." On her first day working on her new team at Uber, Rigetti says, her manager sent her a string of messages propositioning her on the company chat. She says she took screenshots of the conversations, and brought them to Uber's HR department, saying she expected the matter would be handled quickly and appropriately. And from her account, it was not.

Speaking at NATO headquarters in Brussels Monday, Vice President Mike Pence reassured allies that America would uphold its commitments to the organization, but added that President Trump expected "real progress" among NATO allies in stepping up their defense spending.

Defense Secretary James Mattis arrived in Iraq Monday on an unannounced visit that seemed aimed to reassure Iraqi allies. He told reporters that, despite President Trump's earlier statements to the contrary, the U.S. does not plan to seize Iraqi oil.

"All of us in America have generally paid for our gas and oil all along and I'm sure that we will continue to do so in the future," Mattis said. "We're not in Iraq to seize anybody's oil."
