Britain should apologize for its 1917 declaration endorsing the founding of a Jewish homeland in Palestine and should recognize Palestine as a state, Palestinian President Mahmoud Abbas said on Thursday.

Speaking at the U.N. General Assembly, Abbas said that the Palestinian people had suffered greatly because of the Balfour Declaration in which Britain said it favored the establishment of a national home for the Jewish people in Palestine but that this should not undermine the rights of others living there.

"We ask Great Britain, as we approach 100 years since this infamous declaration, to draw the necessary lessons and to bear its historic, legal, political, material and moral responsibility for the consequences of this declaration, including an apology to the Palestinian people for the catastrophes, misery and injustice this declaration created and to act to rectify these disasters and remedy its consequences, including by the recognition of the state of Palestine," Abbas said. "This is the least Great Britain can do."
