US envoy George Mitchell's latest round of shuttle diplomacy in the Middle East has ended without agreement, Palestinian officials said, BBC reported.
Mr Mitchell had met Israeli Prime Minister Benjamin Netanyahu in Jerusalem in a fresh attempt at getting a deal on Jewish settlement activity.
He also went to the West Bank to speak with Palestinian leader Mahmoud Abbas.
Mr Mitchell was hoping for a consensus before all sides attend the UN General Assembly in New York next week.
Palestinian negotiator Saeb Erekat said: "There is no agreement yet with the Israeli side and no middle ground solution."
An Israeli official was reported to have suggested that there may be a hiatus is settlement building in the West Bank, not including East Jerusalem, a little longer than previously offered.
"Israel will agree to extend the freeze beyond six months - possibly nine months, but less than a year," the official said according to the Reuters news agency.
Mr Mitchell had prolonged his trip to the Middle East for several days as he pushed for a deal on freezing Israeli settlement activity in the occupied West Bank.
The US is seeking a moratorium on settlement building that would be acceptable to the Palestinian side.
Mr Abbas and the US administration have been demanding a complete freeze on Israeli construction activity.
Mr Netanyahu had previously offered a temporary freeze for several months, but not in East Jerusalem or in cases where homes have already been approved.
"There is a slowdown in settlement construction, but not a freeze," he said. "There are 2,400 units being built, and their construction will continue."
