Prior to the meeting, the Tunisian President received Arab interior ministers. Then, President Al-Baji Qaid as-Sibsi and Crown Prince Mohammed bin Naif bin Abdulaziz, opened Prince Naif bin Abdulaziz Gallery at the council's secretariat headquarters in recognition of his great deeds for the Arab nation. Addressing the meeting, Crown Prince Mohammed bin Naif bin Abdulaziz, Deputy Premier and Minister of Interior of the Kingdom of Saudi Arabia, said the Arab nation is facing great and serious challenges targeting the security and stability of its well-being. At the outset of his speech, Crown Prince Mohammed bin Naif bin Abdulaziz conveyed to the conferees the greetings of the Custodian of the Two Holy Mosques King Salman bin Abdulaziz Al Saud, lauding the great efforts they are exerting to achieve Arab joint security and enhance their steadfast for the Arab stability and security. In his own name and on behalf of the Arab interior ministers, he forwarded thanks to the leadership, government and people of the Republic of Tunisia for the warm welcome and generous hospitality accorded to the delegates since their arrival, paying special tribute to Tunisia's interior minister Al-Hadi Magdoub for the well done organization of the event and effort exerted to secure comfort for the participants. He said pointed out to a two-pronged challenge facing the Arab nation: internal and external. He said about the internal outlawed that they are deviants from the correct way, following the devil and should be confronted decisively. The outsiders are led by greedy circles who target the destabilization of the Arab nation, threatening its well-being, trying to seize its wealth, and send its peoples to poverty, illness and hunger situations, he said, adding that they are using sectarian differences in the region as well as political and economic motives. In case such challenges were not met with the needed firmness and decisiveness, all components of our Arab nation would face painful results, he said, adding that "we have to shoulder very great responsibilities before our leaders". --More 17:22 LOCAL TIME 14:22 GMT www.spa.gov.sa/w
