Fatah yesterday called on Palestinians to support Jerusalem as news has circulated that the US is to announce it the capital of Israel and would move its embassy there, Quds Net reported.
The movement called on the international community to work to undermine the "frenzied" US plan.
In a statement, Fatah said: "This fierce and systematic attack on Jerusalem, which is being launched by Israel… This attack seeks to erase the Arabic and Islamic existence in the city and Judaise it, as well as change the geographic and demographic reality in a way that serves the expansionist Israeli interests."
The statement added: "Jerusalem is the gate to war and peace. Continuous escalation against its Arabic identity is considered an alarm of war and this abandons all international agreements and conventions."
Such an American step, the statement said, gives a "political and legal legitimacy" to the occupation and "enables it to control the holy sites without any observer".
