A fun family evening for a group celebrating a bar mitzvah turned scary as five Molotov cocktails were thrown at their bus outside the Hebrew University of Jerusalem campus on Mount Scopus on Thursday night.

The attack, which took place shortly after 6:30 pm, left the bus’s windows scorched, but failed to cause extensive damage. The group had opted to take the opportunity to travel around Jerusalem while together for the family celebration.

Yosef Condiotti, a student at the university who rushed to the scene, told the Times of Israel that the passengers were in shock. “It was a lucky escape,” he said. “It could have ended up so much worse.”

To students attending the university, such occurrences are nothing new; students recently took to the streets to protest such attacks. Following that demonstration, student representatives met with senior university and police officials in a bid to increase security in and around the campus.

Itai Gutler, head of the university’s student union, condemned what he called the continued inaction of the authorities to ensure that the area is safe for students and visitors, but expressed hope that the situation will improve.

“I spoke with the senior [police] officials again today, and the police are beginning to internalize the magnitude of this problem,” Gutler said. “It won’t be simple and this definitely is not the end, but we’re starting to make progress. It’s important to keep a finger on the pulse and keep up the pressure,” he wrote in a post to fellow students on Facebook.

Following the incident, police officers scoured the area but no suspects have been identified at present.
