Dozens of firefighters spent three hours overnight Tuesday battling a large blaze that broke out near a hospital and military base on Jerusalem’s Mount Scopus that authorities suspect was deliberately started in an arson attack.

According to the Fire and Rescue Service, two fires broke out in the area just before 10 p.m. and were bolstered by high winds, threatening the Hebrew University Mount Scopus campus and the adjoining Hadassah Medical Center, as well as the nearby Ofarit Base.

The Israel Fire and Rescue Service said 25 firefighter crews aided by police and soldiers tackled the fire at the hospital and the base.

In a statement, the service said the fire started “on the southern slopes of the village of Issawiya, apparently due to the throwing of Molotov Cocktails, and progressed at great speed due to the winds” toward the hospital and the base.

“Multiple firefighting teams from all stations in the Jerusalem District were dispatched to the scene, and were later joined by teams of firefighters from the Central District,” it said.

There were no reports of damage to buildings or injuries, and police said in a statement that at no point was there immediate danger to the university, the army base, or residential areas.

Police opened an investigation into the incident.

Earlier this month, people from the Arab neighborhood of Issawiya threw firebombs at the base, causing no damage or injuries, the Walla outlet reported.

At the beginning of the month, a large fire broke out in a valley near the Israel Museum in Jerusalem, resulting in damage to the roof of its youth wing and the evacuation of the museum.

The cause of the fire was not immediately clear, but unseasonably high temperatures were recorded across the country that day, with the Jerusalem area reaching a high of 93°F (roughly 34°C).

The fire service suspects that it may have been arson, as the blaze apparently started in several locations at the same time.
