Palestinian President Mahmoud Abbas

Palestinian Foreign Minister, Riyad al-Maliki, said on Tuesday that the U.S. President Donald Trump’s decision to halt funding to UN Palestinian refugee agency UNRWA was an attack on international law.

“The U.S. administration has begun to attack the Palestinian people and international law,” Malki said at a meeting of the Arab League in Cairo convened to discuss the issue.

Washington said in August it halted all funding to a UNRWA and Trump on Saturday ordered that 25 million dollars earmarked for the care of Palestinians in East Jerusalem hospitals be directed elsewhere as part of a review of aid.

UNRWA is seeking to make up a 200 million dollars shortfall caused by the U.S. aid cutoff, and said it will target additional funding from Gulf states and European partners.

Washington’s decision has further heightened tensions between the Palestinian leadership and the Trump administration, which in December recognised Jerusalem as the capital of Israel, a move criticised by the international community.
