Jeon Chung-won tends sheep on the hilly farm where he was born in PyeongChang, a rural county a few hours' drive east of South Korea's capital Seoul.

"It's a simple, peaceful place where the mountain air hugs you," says Jeon, 32. "I really love this place."

Only a handful of domestic tourists typically come to PyeongChang, to hike green hills dotted with Buddhist temples or visit a small ski station nearby. But that is about to change.

Social media companies are under pressure to block terrorist activity on their sites, and Facebook recently detailed new measures, including using artificial intelligence, to tackle the problem.

The measures are designed to identify terrorist content like recruitment and propaganda as early as possible in an effort to keep people safe, says Monika Bickert, the company's director of global policy management.

Iraq's military said ISIS destroyed the 12th century al-Nuri mosque in Mosul's Old City, where ISIS fighters remain, on Wednesday.

The Great Mosque of al-Nuri, a medieval mosque with the tall, leaning al-Hadba minaret, was the site where ISIS leader Abu Bakr al-Baghdadi made a rare public appearance and, in July 2014, declared the group's "caliphate" in Iraq and Syria.

Seventeen-year-old Nabra Hassanen was buried Wednesday after a funeral service packed with mourners. The service was held in the Northern Virginia community where she'd lived. An evening vigil organized by her high school's Muslim Student Association also drew throngs of people.

Hassanen was beaten and killed early Sunday morning as she walked back to her mosque after a pre-dawn meal with friends. Such meals are common during the month of Ramadan, when many Muslims fast from dawn to sundown.

Democratic finger-pointing has begun after the party's loss in Tuesday's closely watched special election in Georgia, and for some members, the blame partly belongs to their House minority leader, Nancy Pelosi.

Eye-popping. That's the word that comes to mind when you hear how many viruses are likely hiding out around the world in animals.

"We expect there are hundreds of thousands of mammalian viruses out there," says Kevin Olival, a disease ecologist at EcoHealth Alliance, who led the study.

Really? Hundreds of thousands?

"Yes, it's likely," Olival says. "Any given mammal species is likely to have 20, 30 or even 100 viruses. When you add that up around the planet, you get a big number."

Saudi Arabia, a close ally of the United States, is not known for surprises. But in a sudden shift in power, the 31-year-old son of the 81-year-old Saudi king moved one step closer to the throne on Wednesday.

King Salman bin Abdul-Aziz Al Saud promoted Mohammed bin Salman, his youngest son, to crown prince. At the same time, the king ended the career of his nephew, 57-year-old Mohammed bin Nayef, the previous crown prince, who had served as interior minister since 2015.

Summer officially began at 12:24 a.m. ET Wednesday, but as the Southwestern United States bakes in a heat wave, the season may already feel like a long and sweltering slog there.

In a letter to White House chief of staff Reince Priebus, the oversight panel's 18 Democrats question why Kushner's security clearance hasn't been revoked.
