Protesters march in a street in al-Habileen city, in the southern Yemeni province of Lahj October 6, 2009. Arab League chief Amr Moussa said on Tuesday Arab states supported the unity of Yemen, which faces a Shi'ite rebellion in the north and secessionist unrest in the south. The United States and Saudi Arabia, the world's leading oil exporter, fear that a northern war between the army and Zaydi Shi'ite Muslims, as well as frequent street clashes with separatists in southern Yemen, could create instability that al Qaeda could exploit to carry out attacks.
