The difficulties facing the Salek government multiplied and soon proved to be insurmountable. His regime failed to overcome Morocco's resistance to any settlement of the Western Sahara conflict. The death of Algerian president Houari Boumediene in December 1978 further heightened tensions. Also, Senegalese president Leopold Senghor, who was displeased with Salek's ties with Morocco, instigated a press campaign that highlighted racial problems in Mauritania. Salek did little to ease the racial problem when, in March 1979, he named eighty-one Maures and only seventeen blacks to his new national advisory committee. Finally, the French government lost confidence in Salek's ability to extricate Mauritania from both the Western Sahara war and Moroccan influence. Isolated and weak, Salek's government was overthrown on April 6, 1979, by Colonel Ahmed Ould Bouceif and Colonel Mohamed Khouna Haidalla, who formed the Military Committee for National Salvation (Comité Militaire de Salut National--CMSN). Salek, however, was permitted to remain in the government as a figurehead president. In late May, Bouceif was killed in an airplane crash Haidalla was designated prime minister, and Colonel Mohamed Louly was named president.
