The Quartet of international powers has "lost its grip" on the Middle East peace process which it is meant to foster, a group of aid agencies says.
In a damning report, the agencies say the Quartet - Russia, the US, the EU and the UN - is failing in its mission.
Conditions for Palestinians, which it was meant to improve, have worsened since peace talks recommenced under US sponsorship in 2007, the agencies say.
In the West Bank there was an increase in Israeli settlement and travel curbs.
The report was issued ahead of a Quartet meeting in New York on Friday.
"The Annapolis process [launched by the US in November 2007] was meant to herald a new dawn for the Middle East peace process," said Christian Aid director Daleep Mukarji.
"Nearly one year on, we are seeing exponential settlement growth, additional check-points and - because of this - further economic stagnation.
"The Quartet is losing its grip on the Middle East peace process."
There has been no immediate response from the Quartet, whose representative in the region is former UK Prime Minister Tony Blair.
