A nightclub in Jerusalem’s French Hill neighborhood was firebombed at around midnight Saturday night, police said Sunday morning.

One person was lightly injured from smoke inhalation in the attack.

Arrests have been made in the case and police are working on determining if the attack was criminal or politically motivated.

Just before midnight, three Molotov cocktails were thrown at the club, which is in an area frequented by students from the nearby Mt. Scopus campus of Hebrew University, police spokesman Micky Rosenfeld told the Times of Israel.

He added that police opened an investigation into the attack and “three suspects were arrested for being connected to the incident” following a search of the area.

MK Ayelet Shaked (Jewish Home) decried the incident as a “terror attack in the capital” and said that the enforcement of laws against throwing Molotov cocktails was “incomplete.”

Authorities were still trying to determine if the bombing was criminal or a terror attack. The French Hill area has seen numerous firebombings and incidents of stone throwing in the past, mostly perpetrated by residents of adjacent Arab neighborhoods and often directed at students at the university, many of whom live in nearby dormitories.

There was a surge in petrol bombings and stone throwing incidents around French Hill in January and February, police said, and then after an investigation 16 arrests were made. Since then it has been “relatively quiet, and obviously yesterday’s incident is something that was rather extreme,” the police spokesman added.

A man was lightly injured in a Thursday incident at a gas station in French Hill, police said. Israel National News reported Sunday that the victim was Raphael Delarosa of Jerusalem, who was attacked while driving by a group of rock-throwing Arab youngsters.
