Jerusalem Mayor Moshe Leon responded by hanging the PLO flag on the Old City walls.
"The only sovereignty in Jerusalem is Israeli sovereignty. I will not allow any organization to try to step foot in the city. We will stand firm in the face of anyone trying to challenge the sovereignty of the State of Israel in Jerusalem," he said.
Leon added: "As soon as the flag was hung, the municipal inspectors identified the perpetrator and in rapid cooperation with the Israeli police the flag was immediately removed."
