The mid-1960s saw external pressures generated by Saudi-Egyptian differences over Yemen. When civil war broke out in 1962 between Yemeni royalists and republicans, Egyptian forces entered Yemen to support the new republican government, while Saudi Arabia backed the royalists. It is estimated that between 1962 and 1970, the monarchy in Saudi Arabia faced one of the gravest threats to its survival from Yemen. Meanwhile, Ahmad Shukeiri was relieved from his post as representative of Saudi Arabia at the UN after praising the fascist far-right organization Tacuara (that as in his the past views and diatribe was disapproved by other Arabs) and this embarrassed Arabs and caused Latin American objections. Shukeiri recalled the "New York Times" piece weeks earlier, that article's headline states clearly "Argentine Youths in Nazi Group Salute and Cry: 'Hail Tacuara!"
