United Nations Security Council resolution 660, adopted on 2 August 1990, after noting its alarm of the invasion of Kuwait by Iraq, the Council condemned the invasion and demanded Iraq withdraw immediately and unconditionally to positions as they were on 1 August 1990. Yemen called upon Iraq and Kuwait to enter into immediate negotiations to resolve their differences, thanking the Arab League for its efforts. Talks between both sides broke down the day before in Jeddah, Saudi Arabia. The Council also decided to meet again as necessary to ensure compliance with the current resolution.
