A Greek Orthodox seminary in Jerusalem was burned Thursday and anti-Christian graffiti was sprayed on a nearby wall.

Police in the area say it’s clearly a hate crime.

The bathroom and corridor of Dormition Abbey was set on fire around 3 a.m. by unknown assailants.  As firefighters extinguished the flames, they saw the crudely written graffiti mocking Jesus Christ.

A court has issued a gag-order for most of the details of the crime but a witness shared what they saw about the attack.

“Two people who were hiding their faces came from the east side of the structure near the cemetery and the Catholic church,” he said. “From there they threw flammable liquid at the seminary’s bathroom.”

Israeli President Reuvin Rivlin was outraged by the attack.

“It is inconceivable that an act like this could happen in a house of prayer,” Rivlin said in a statement.

“This is a heinous crime, there must be an investigation and those responsible must be brought to justice. Such criminals not only threaten to set fire to places of worship holy to all of us, but ignite the regional powder keg upon which we all sit.”
