5 Things to Know This Morning

— -- Your look at the five biggest and most buzz-worthy stories of the morning.

1. American Doctor With Ebola Will Be Released From Hospital

An American doctor who contracted Ebola will be released today from Emory University Hospital in Atlanta, ABC News has learned.

Dr. Kent Brantly, 33, contracted the deadly virus while working in a Liberian Ebola ward with the aid agency Samaritan’s Purse. He was evacuated to the U.S. earlier this month along with coworker Nancy Writebol.

2. US Military Launched Secret Rescue Operation in Syria for James Foley, Other Americans

U.S. special operations forces early this summer launched a secret, major rescue operation in Syria to save James Foley and a number of Americans held by the extremist group ISIS, but the mission failed because the hostages weren’t there, senior administration officials told ABC News today.

President Obama authorized the “substantial and complex” rescue operation after the officials said a “broad collection of intelligence” led the U.S. to believe the hostages were being held in a specific location in the embattled Middle Eastern nation.

When “several dozen” U.S. special operation members landed in Syria, however, they were met with gunfire and “while on site, it became apparent the hostages were not there,” one of the officials said. The special operators engaged in a firefight in which ISIS suffered “a good number” casualties, the official said, while the American forces suffered only a single minor injury.

The American forces were able to get back on helicopters and escape.

“Intelligence is not a perfect science,” the senior official said. As to how the intelligence failed and why the hostages were not there, the official said, “The truth is, we don’t know. And that’s the truth. When we got there, they weren’t there. We don’t know why that is.”

3. Girlfriend at Center of Gainesville Love Triangle Never Thought Killer Ex Was Capable of Murder

The ex-girlfriend of Pedro Bravo, the Florida college student who was found guilty last week of killing her new love in the so-called Gainesville Love Triangle trial, said she never thought the smart, charismatic student she once dated was capable of murder.

“He kind of tricked us all, thinking, you know, this guy that’s shy and he wouldn’t hurt a fly,” Erika Friman told ABC’s Matt Gutman in an interview for “20/20.” “I don’t think anyone in their right mind would go as far as he has.”

4. 'A Very Good Night' in Ferguson as Peace Preserved

Peaceful protests and community activism replaced violent clashes in the streets of Ferguson, Mo. overnight, with only six arrests reported, police said.

Unrest has ruled in the St. Louis suburb since the Aug. 9 police shooting death of unarmed teen Michael Brown.

Missouri Highway Patrol Capt. Ron Johnson, speaking at an early-morning news conference, said tonight’s protesters remained mostly orderly, showing a marked improvement over the previous night, when 47 people were arrested.

“Tonight was a very good night,” Johnson said.

5. How Real Is the Looming Nutella Shortage?

Chicken wings, limes and now Nutella: even in the wealthiest country in the world, many Americans get worked up over food shortage scares that pop up a few times a year.

But in most cities in the U.S., the rumors are usually more hype than fact.

How real is the reported threat to Nutella hazelnut spread? Somerset, New Jersey-based Ferrero USA, the company that makes and distributes the sweet stuff for its Italian parent company, says fans have no need to worry. That's in spite of the poor weather in Turkey, where approximately 70 percent of the world's hazelnuts originate, according to the Financial Times.

"Inclement weather last spring in Turkey has impacted this year’s hazelnut harvest," a spokesperson for Ferrero USA said in a statement to ABC News. "We are tracking this issue closely and there’s no foreseeable impact on the availability of Nutella. As always, we will maintain the high quality of the Nutella product that consumers know and love."
