Taylor Force, a student from the US, was killed in a mass attack in Israel by a Palestinian man on Tuesday. The attackers also injured at least 13 others in a spate of three attacks over one and a half hours.

Force, 28, was a first year MBA student of Vanderbilt University in Nashville, Tennessee, and who came to Israel on a school trip with the Owen Graduate School of Management.

“Taylor embarked on this trip to expand his understanding of global entrepreneurship and also to share his insights and knowledge with startups in Israel,” a statement issued by Vanderbilt University read, as quoted by The Guardian. “He exemplified the spirit of discovery, learning and service that is the hallmark of our wonderful Owen community. This horrific act of violence has robbed our Vanderbilt family of a young hopeful life and all of the bright promise that he held for bettering our greater world.”

The statement added that the other students and staff on the same trip were safe.

The attacks took place in in East Jerusalem, Petah Tikva, and Jaffa on Tuesday evening. The attackers had guns and knives which they used against both police and passersby. The attacks were carried out a little after US vice  president, Joe Biden, arrived for a two-day trip to Israel and Palestine. He will be meeting Palestinian President Benjamin Netanyahu and President Mahmoud Abbas on Wednesday.

The New York Times reported that according to Force’s LinkedIn profile, he served as an army officer from 2009 to 2014, which included trips to Iraq and Afghanistan.

“We have been notified, and we have no details about anything,” The New York Times quoted Force’s father as saying.

According to The Guardian, a video footage of the incident showed a man in dark trousers and grey hooded top running beside a traffic jam seemingly trying to attack the occupants of the cars through an open window. The Guardian report also stated that according to the Magen David Adom ambulance service, four of the wounded have suffered severe injuries.
