In the region around the holy Al-Aqsa Mosque there is a state of high tension, uncertainty and caution that Jewish groups will enter the Mosque and desecrate its dignity and prestige.They are not worried about "Zionists" taking control of the Temple Mount. They are not accusing Jews of impacting their freedom of worship. They are not saying that these groups will scrawl graffiti, or tear up Qurans, or throw stones at Muslims in the mosque.
To them, the very existence of Jews in the most holy of Jewish places is, in itself, a "desecration."
