The political and financial crisis deteriorated after the European Union and the United States suspended direct aid to the cash-strapped Hamas-led government in addition to Israeli freeze on transferring tax payment to the Palestinian Authority following Hamas election victory in January.

Abdel Rahman told the Ramallah-based al-Ayyam daily that this crisis has started to get worse with unprecedented siege. He said that the dialogue was aimed at getting out of confusion and randomness.

"We need a responsible session with our brothers in Hamas movement and we want them to succeed but the conditions to succeed are in their hands because President (Mahmoud) Abbas offered them all possible assistance," said Abdel Rahman.

He asserted that the crisis was a political one and Hamas has to differentiate between its program as a resistance movement and the national program (to seek a negotiated solution to the Palestinian-Israeli conflict).

"Without abiding by the national program and the signed accords, we cannot see any hope in knocking on the (donors') doors that are closed to the government and the Palestinian people," he said.

"Hamas needs to make a quick review of its positions otherwise the crisis would escalate and the President (Abbas) or Fatah will not be blamed for that," he added.

The former ruling Fatah led by Abbas was defeated by Hamas in the Jan. 25 legislative elections.

Hamas, sworn to the destruction of Israel, has refused to renounce violence, recognize Israel's right to exist and accept previous deals signed with the Jewish state, the conditions set byIsrael and its Western allies for granting aid and contact.
