The Islamic Hamas movement on Thursday accused the Palestinian National Authority (PNA) of striking against the national principles, Xinhua reported.
The accusations were made following Israeli reports which quoted Palestinian president Mahmoud Abbas' spokesman as saying that the PNA was ready to give up control on the al-Aqsa holy mosque's campus in East Jerusalem for a third party if Israel was willing to go ahead seriously in the peace process.
"Such statements pose a strong blow to the Palestinian principles," said Ismail Radwan, a spokesman for Hamas which controls the Gaza Strip. "These statements endanger the principles specially the one of Jerusalem."
Nabil Abu Rdineh, Abbas' spokesman, was quoted by the Israeli newspaper Ha'aretz as saying that the third party must be an Islamic one, such as the Islamic Conference Organization which represents 57 countries, including Iran and Saudi Arabia.
But Hamas also said it does not "count much on the useless negotiations and the compromise solutions," describing such proposals as conspiracies.
