African leaders on Sunday condemned US President Donald Trump’s Mideast peace plan as illegitimate, taking advantage of an African Union summit to voice solidarity with “the Palestinian cause”.

AU Commission Chairman, Moussa Faki Mahamat told assembled heads of state that the plan unveiled in late January represented the “umpteenth violation of multiple United Nations and African Union resolutions”.

He said that it was prepared without international consultation and that it “trampled on the rights of the Palestinian people”, a line that drew applause in the main hall at AU headquarters.

Trump’s peace proposals were immediately rejected when he announced them by the Palestinians, who have boycotted his administration over its pro-Israel stance.

The proposals include giving Israel the green light to annex settlements in the occupied West Bank, the largest part of the territories the Palestinians see as their future state.

Egyptian President Abdel Fattah Al Sisi, said in his remarks Sunday that “the Palestinian cause will always be in the hearts and minds of the people of Africa”.

 South African President Cyril Ramaphosa compared Trump’s proposals to regulations in place during his country’s apartheid period.

“As I listened to it and as I read everything that’s written about it, it brought to mind the horrible history that we in South Africa have gone through,” he said.

Palestinian President Mahmoud Abbas, who was represented on Sunday by Palestinian Prime Minister Mohammad Shtayyeh, reiterated Palestinian leaders’ position that the Trump plan “has no legitimacy whatsoever”.
