Iranian President Mahmoud Ahmadinejad on Sunday proposed a "simple solution" to the Palestinian-Israeli conflict under which "everyone should go home."
"If the backers of the Zionist regime want to solve the issue... the solution is simple ... everyone should go home," he told an international conference, as the United Nations mulls a Palestinian statehood bid.
"Some poor people were brought to Palestine on the promise of security and jobs while they made Palestinian people into refugees... So now Palestinians should go home and those brought here should go to theirs," he said.
