A coalition of aid organisations has charged the so-called Quartet of Middle East negotiators with failing to make significant progress towards peace in the region.
The 21 agencies issued their report on Thursday saying the EU, Russia, the US and the UN had not delivered on half of their goals, and that in some instances, the situation had become worse since the much-hyped Annapolis conference last year.
The report cited accelerated expansion of illegal Israeli settlements on occupied Palestinian land, despite at least 18 calls for the contrary by the Quartet, as one of the points of deterioration.
Additionally, it says Israeli restrictions on movement in the occupied West Bank continue, and that an Israeli-led blockade of the Gaza Strip has not been eased, despite a ceasefire between Israel and Hamas.
Roadblocks
In an interview with Al Jazeera last week, Tony Blair, the so-called special envoy of the Middle East Quartet, claimed that roadblocks in the West Bank are slowly being removed.
He said: "We are working now, not just with the Palestinians but with the Israelis, to try to move those roadblocks, to get them progressively lifted.
"For example, in and around the Jenin area ... what we're trying to do is deliver a different form of security operations so that the Palestinians take charge of their security."
Under mediation in the West Bank city of Jenin, the Israeli military has pulled back, allowing Palestinian security forces to assume more control in the city.
The report was released on the eve of a meeting of the Middle East Quartet in New York. The groups criticising its performance include CARE International UK, Oxfam and Save the Children UK.
Salaam Kannan, director of Save the Children UK's programmes in the West Bank, told Al Jazeera that the Quartet needed to "formulate an action plan to reassess its performance, to acknowledge its shortcomings and to hold all parties to the conflict accountable".
She acknowledged that some improvements had been made, namely "increased fuel to Gaza - though not in sufficient quantities - and improvement in the Palestinian security reform strategy".
