Arab nations that normalized ties with Israel last year have "sinned" and should reverse such moves, Iran's supreme leader Ali Khamenei said on Sunday.
The United Arab Emirates, Bahrain, Sudan and Morocco all said in 2020 they would normalize ties with Israel, as Washington under the administration of then U.S. president Donald Trump made Arab-Israeli rapprochement a foreign policy priority.
"Some governments have unfortunately made errors - have made big errors and have sinned in normalizing (their relations) with the usurping and oppressive Zionist regime," Khamenei said, referring to Israel.
