U.N. Secretary-General Ban Ki-moon regrets a "misunderstanding" over his use of the word "occupation" to describe Western Sahara status, which led to Morocco expelling dozens of United Nations staff, his spokesman said on Monday.
"His use of the word was not planned, nor was it deliberate, it was a spontaneous, personal reaction. We regret the misunderstandings and consequences that this personal expression of solicitude provoked," U.N. spokesman Stephane Dujarric told reporters.
The controversy over Ban's comments is Morocco's worst dispute with the United Nations since 1991, when the U.N. brokered a ceasefire to end a war over Western Sahara and established a peacekeeping mission, known as MINURSO.
Ban said the word during a visit to refugee camps in southern Algeria for the Sahrawi people, who contend Western Sahara belongs to them.
Morocco then ordered the United Nations to pull out dozens of civilian staffers and close a military liaison office for the MINURSO peacekeeping mission. It said its decision was irreversible, but that the government was committed to military cooperation to guarantee a ceasefire.
"Nothing (Ban) said or did in the course of that trip was meant to offend or express hostility toward the Kingdom of Morocco, which is a valued member of the United Nations," Dujarric said.
Rabat has accused Ban of dropping the United Nations' neutral stance on the Western Sahara dispute.
"The position of the United Nations has not changed," Dujarric said. "He has not and will not take sides on the issue of Western Sahara."
U.N. officials had repeatedly urged the U.N. Security Council to publicly voice its support for Ban and MINURSO, which the 15-nation body did late last Thursday in New York.
However, the council did not explicitly order Morocco to reverse its decisions or address Ban's use of the word "occupation."
The U.N. MINURSO mission, which consists of military and civilian staff, monitors the Western Sahara ceasefire and is charged with organising a referendum over the region's future. But deadlock has delayed the vote for years.
