Abbas did not refer to the possibility of extending the talks.
His aides have said he does not want to be blamed for a collapse of the Kerry mission or accept what the Palestinians would consider a bad framework. In such a situation, accepting an extension might be seen as the lesser evil by the Palestinians.
Abbas reiterated that the Palestinians have options if the negotiations don't lead to a deal. He said he would resume their quest for wider U.N. recognition, a step Israel and the U.S. adamantly oppose and that was suspended for nine months of the negotiations. Abbas said the Palestinians could also continue to resist occupation with demonstrations.
He said he does not want to negotiate for the sake of talking.
"I accept a valuable chance (for an agreement) if there really is a valuable chance, not just talk," he said.
