Over 30 armed provocateurs wearing ski masks and some carrying lethal weapons attacked a group of Armenian bishops, priests, deacons, and other citizens on Thursday in the Old City of Jerusalem, according to the Armenian Patriarchate.
“A mass and coordinated physical attack was launched,” the Patriarchate wrote in an official letter to the Police and Israeli government, which The Jerusalem Post reviewed. “Several priests, students, and indigenous Armenians are seriously injured.”
“They attacked us,” Bishop Koryoun Baghdasaryan, director of the Real Estate Department for the Patriarchate, told the Post.
