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

1. Violence in Ferguson: Police Fire Tear Gas, Smoke Bombs at Demonstrators

Violence erupted in the streets of Ferguson, Mo. for a fourth straight night, with police firing smoke bombs and tear gas at demonstrators and some people lobbing Molotov cocktails. Racial unrest lingers in the St. Louis suburb following a weekend police shooting of an unarmed black teenager.

2. Funeral Set for Driver Hit by Tony Stewart's Car

Kevin Ward Jr.'s father and fellow racers want him remembered as a talented and aggressive driver who had a bright future in the sport rather than as a victim in an accident involving NASCSAR champion Tony Stewart that sparked controversy among racing fans and recriminations from Ward's family.

Funeral services for the 20-year-old were set for 11 a.m. Thursday at South Lewis Senior High School in Turin, 55 miles northeast of Syracuse. Ward, a 2012 graduate of the school, lived in nearby Port Leyden.

Ward was killed Saturday night 140 miles away at a dirt track in Canandaigua, where NASCAR champion Stewart was racing while he was in the area for a Sprint Cup event at Watkins Glen the next day. After a bump from Stewart sent Ward's winged car spinning into the wall, the young driver climbed out and stalked onto the track in his black firesuit, gesturing angrily. Stewart's No. 14 car seemed to fishtail, and Ward was thrown through the air as fans watched in horror.

3. Evacuation of Yazidis on Mt. Sinjar in Iraq 'Far Less Likely,' Says Pentagon

An evacuation of thousands of refugees who were forced onto Mt. Sinjar in Iraq is "far less likely" after an assessment by United States Marines, Special Forces and the USAID disaster assistance relief team, the Pentagon said.

Less than 20 personnel briefly landed on the mountain, where thousands of Yazidis are trapped and facing a humanitarian crisis.

"The team has assessed that there are far fewer Yazidis on Mt. Sinjar than previously feared, in part because of the success of humanitarian air drops, air strikes on ISIL targets, the efforts of the Peshmerga and the ability of thousands of Yazidis to evacuate from the mountain each night over the last several days," Pentagon Press Secretary Rear Admiral John Kirby said in a statement. "The Yazidis who remain are in better condition than previously believed and continue to have access to the food and water that we have dropped."

4. Pope to Koreas: Avoid 'Fruitless' Shows of Force

Pope Francis called Thursday for renewed efforts to forge peace on the war-divided Korean Peninsula and for both sides to avoid "fruitless" criticisms and shows of force, opening a five-day visit to South Korea with a message of reconciliation as Seoul's rival, North Korea, fired five projectiles into the sea.

North Korea has a long history of making sure it is not forgotten during high-profile events in the South, and Thursday's apparent test firing off its eastern coast made its presence felt.

In the first speech of his first trip to Asia, Francis told South Korean President Park Geun-hye and government officials that peace required forgiveness, cooperation and mutual respect. He said diplomacy must be encouraged so that listening and dialogue replace "mutual recriminations, fruitless criticisms and displays of force."

5. Drunk Without Alcohol: Strange Condition Ferments Food in Gut

Nick Hess lives an active lifestyle, biking, swimming and playing volleyball. But three years ago, the 34-year-old waiter practically collapsed onto the floor with intense stomach pain.

“[I] thought maybe I had a stomach bug or something. It was terrible,” Hess told ABC News’ “20/20.”

Actually, he had auto-brewery syndrome, which causes the stomach to use excess yeast in the intestine to ferment carbohydrates and other sugary foods into alcohol.
