The UN Security Council will convene Sunday to discuss the security situation in Yemen, after Yemeni President Abed Rabbo Mansour Hadi asked the Council to "intervene quickly" to solve the crisis, Reuters reported. Hadi accused the Houthi militants, who control the capital, Sanaa, of organizing a coup against the country's legitimate authorities, adding that he will raise the Yemeni flag on the rebels' stronghold in northern Yemen. He asked the UN Security Council in a letter to "quickly intervene by all means available to stop this aggression, which aims to undermine the legitimate authority and jeopardize Yemen's safety and stability." He also called on the Security Council to "deter the Shi'ite militia and its allies, in addition to stopping their aggression on all Yemeni provinces, particularly on the city of Aden. The council should carry out its responsibilities to protect the security and legitimacy of Yemen." Diplomats, who asked to remain anonymous, told Reuters that the Security Council will negotiate a resolution for the Yemeni crisis that might be endorsed at the convention. Yemen has been sliding into civil war since 2014, after the Houthi rebels seized control of Sanaa and clashed with local Sunni tribes.
