United Nations Security Council resolution 619 was a resolution adopted unanimously on 9 August 1988 by the United Nations. The resolution came after recalling Resolution 598 (1987) and approving a report by the Secretary-General Javier Pérez de Cuéllar on the implementation of paragraph 2 of Resolution 598. The Council therefore decided to establish the [United Nations Iran–Iraq Military Observer Group](https://bliptext.com/articles/united-nations-iran-iraq-military-observer-group) for an initial period of six months to monitor the ceasefire between Iran and Iraq at the end of their conflict.
