More than 150 people were killed in the Halloween stampede in Seoul, South Korea, including two U.S. college students studying abroad.

Steven Blesi was an international business major attending Kennesaw State University, which is located outside Atlanta, and Anne Gieske was a nursing student at the University of Kentucky. Both students were 20 years old.

Among the 153 reported deaths from Saturday night's crowd surge, more than 80% were in their 20s and 30s, and at least four were teenagers. 

Seoul officials said Sunday that 26 of the deceased were foreigners, including from the U.S., France, Thailand and Japan. A total of 97 women and 56 men were confirmed dead. Officials said 133 people were also injured that night.

Blesi was one of 11 KSU students studying abroad in Seoul, but his classmates were all reported safe after the incident.

"On behalf of the entire Kennesaw State community, our thoughts and prayers go out to Steven’s family and friends as they mourn this incomprehensible loss," Kennesaw State University President Kathy Schwaig said in a statement.

Schwaig also said, "We have been in contact with Steven’s family and have offered all available resources of the University to them."

Blesi was about two months into a semester studying abroad at Hanyang University. He was interested in pursuing international business in East Asia upon graduation.
