MINURSO observers confirmed the departure of Polisario elements on 27–28 April. The standoff had developed in 2016 around the road crossing the buffer strip towards Mauritania.

It noted that the crisis raised fundamental questions about the ceasefire and related agreements. Local de-escalation therefore settled neither the political dispute nor all questions about permitted activities in the area.
