Mahmoud Abbas lambasted the US’s decision to recognise Jerusalem as Israel’s capital and drastically cut aid to the Palestinians, saying it had undermined a two-state solution to the conflict.

The Palestinian President said that the measures demonstrated Donald Trump was “biased” towards Israel and needed to be reversed.

“With all of these decisions, this administration has reneged on all previous US commitments, and has undermined the two-state solution,” Mr Abbas told the UN General Assembly last week.

“I renew my call to President Trump to rescind his decisions and decrees regarding Jerusalem, refugees and settlements.”

He added that he would not accept sole US mediation in the peace process.

“It’s really ironic that the American administration still talks about what they call the ‘deal of the century’,” he said. “But what is left for this administration to give to the Palestinian people? Only humanitarian solutions?”

Mr Abbas’s speech came as the leadership of Hamas, which is in effective control of the Gaza Strip, the Palestinian President to lift what they described as “sanctions” on the territory.

Mr Abbas and his rival Fatah movement, which controls the Palestinian Authority, has slashed funding civil servant salaries in Gaza in an effort to pressure Hamas into handing over control of the territory.

Hamas has controlled Gaza since it violently seized control in 2007 and recent efforts to broker a truce with Fatah, brokered by Egypt, have not succeeded.
