Muslim writings were graffitied Thursday in the entrance hall of a synagogue in moshav Maor in central Israel. Police have launched an investigation into the vandalism but do not have any suspects.

The Menashe Regional Council’s security officer told Israel’s Channel 10 news that congregants had arrived for evening prayers at the synagogue and discovered the damage.

The graffiti was part of a prayer and read “There is no God but Allah and Mohammed is his prophet.”

On Tuesday,  Hebrew graffiti reading “The war has just begun” and “You will pay the price” was found spray painted on a burnt mosque in the Palestinian village of Jaba, near Ramallah in the Binyamin region of the West Bank.

Police and Shin Bet launched an investigation into the incident and suspect right-wing extremists are behind it.

Prime Minister Benjamin Netanyahu condemned the Jaba attack in no uncertain terms, calling it “an irresponsible act of lawlessness and intolerance,” and pledged to “act swiftly to bring the culprits to justice.”
