The Arab League said Thursday it would hold an emergency meeting over the increasing violence between Sudan and South Sudan. Sudan President Omar al-Bashir on Wednesday threatened to topple the South Sudan government after accusing the south of trying to take down his Khartoum-based government. Al-Bashir continued his hardline rhetoric on Thursday in an address to a "popular defense" brigade headed to the Heglig area. The ceremony was held in al-Obeid, in northern Kordofan.
