A video has emerged that purports to show militants of the self-declared Islamic State beheading 21 Egyptian Christians kidnapped last week in Libya.

Reuters reports: "In the video, militants in black marched the captives, dressed in orange jump suits, to a beach. They were forced down onto their knees, then beheaded."

Reuters says a caption on the five-minute video reads: "The people of the cross, followers of the hostile Egyptian church."

The headquarters of the National Oil Corporation in Tripoli are gleaming, the floors marble, the offices decked out with black leather chairs and fake flowers. It seems far from the fighting going on over oil terminals around the country.

But the man in charge looks at production and knows the future is bleak.

"We cannot produce. We are losing 80 percent of our production," says Mustapha Sanallah, the chairman of Libya's National Oil Corporation.

He looks like a typical executive, decked out in a suit and glasses. But beneath his calm veneer, he's worried.

The Federal Aviation Administration has released long-awaited draft rules on the operation of pilotless drones, opening the nation's airspace to the commercial possibilities of the burgeoning technology, but not without restrictions.

House Speaker John Boehner says he's prepared to let the Department of Homeland Security run out of money to push the Republican majority's efforts to reverse President Obama's immigration initiative.

Joshua Starr, a nationally prominent superintendent with the Montgomery County schools in Rockville, Md., this month was granted early release from his contract after 3 1/2 years.

Outrage over the murder of three young Muslim Americans in North Carolina last week has gone international. The Organization of Islamic Cooperation said Saturday that the killings reflected "Islamophobia" and "bear the symptoms of a hate crime," but local authorities say they don't yet know what motivated the murders.

The man held responsible for the killings is an avowed atheist. Whether that's relevant in this case is not clear, but some experts see a new extremism developing among some atheists.

The fourth winter storm in the Northeast this year was adding to the 6 feet of snow already on the ground in some areas, bringing with it hurricane-force winds and near-white-out conditions.

In Massachusetts, Gov. Charlie Baker said at a news conference early today that snowfalls had already "significantly exceeded" expectations. Accumulation in the northern half of the state exceeded a foot in some places.

The cease-fire in eastern Ukraine appears to be largely holding — at least for the moment, defying skepticism that the second truce in six-months between government forces and Russian-backed separatists might immediately collapse.

The cease-fire went into effect at midnight Sunday (Saturday at 5 p.m. ET).

Jack White, formerly of the White Stripes, must really hate bananas. Because according to his concert rider, which was recently made public, he doesn't want to lay eyes on one at his concerts.

If you want to see what George Washington might have munched on, then Sandy Levins is your gal. All the food she whips up look scrumptious, but if you sneak a bite, you'll get a mouthful of plaster or clay.

Levins is one of a handful of frequently overlooked artisans who craft the replica meals you see in the kitchens and dining rooms of historic houses and museums. Adding faux food to a historical site can help visitors connect to the past, she tells The Salt.

"It's something everyone immediately identifies with, because everyone eats," she says.
