East Jerusalem Was A Capital?

UPI copies a report from Haaretz which copied it from Al-Ayyam:-

A Palestinian official says leaders may ask the U.N. Security Council to recognize a de facto Palestinian state based along 1967 boundaries.

Speaking to the Palestinian newspaper al-Ayyam, senior negotiator Saeb Erekat said the Palestinian Authority is hoping to obtain the Security Council's backing for a state that would include all Palestinian areas held prior to the 1967 Arab-Israeli War and that had East Jerusalem as its capital, the Israeli newspaper Haaretz reported Saturday.

Prior to 1967?

How far back is that "prior to 1967"?

And East Jerusalem was not the capital of any "Palestinian area".

Propaganda is good for all ills.
