NOUAKCHOTT, Sept 21 (MENA) - Mauritanian President Mohamed Ould Abdel Aziz on Friday said that the terrorist Muslim Brotherhood (MB) group is behind all problems in the Arab countries. Addressing a press conference, the first after his reelection as president of the country, he added it is true that the Arab world's tragedies are due to the occupation of Palestine but these tragedies have aggravated more and more due to using religion in politics by the terrorist group. This state of affairs served only Israel and led to the destruction of Arab countries, he pointed out. He further noted that his country will not allow using religion to achieve political goals.
