But Mr Abbas apportioned blame all round in a private session of parliament on Saturday. A statement from his office said he told MPs: "The fundamental problem is Israel's unwillingness to implement its road map commitments and to undertake any constructive measures."
"The US (and the international community) did not exert sufficient influence on Israel to implement its commitments in the road map to push the peace process forward, or to end its military escalation."
Mr Abbas was also scathing about Mr Arafat and his allies. He accused them of "harsh and dangerous domestic incitement against the government and the obstruction of its functions" and said they were responsible for "unjustified accusations that the government, and the prime minister, had the motive of having control over everything or nothing".
