evidence: The Heglig Crisis[18] was a brief war fought between the countries of Sudan and South Sudan in 2012 over oil-rich regions between South Sudan's Unity and Sudan's South Kordofan states. South Sudan invaded and briefly occupied the small border town of Heglig before being pushed back by the Sudanese army. Small-scale clashes continued until an agreement on borders and natural resources was signed on 26 September, resolving most aspects of the conflict. [...] On 15 April 2012, the Arab Parliament called on South Sudan for restraint and to withdraw from the town of Heglig. A statement signed by Arab Parliament head Salem Deqbasi said that the Arab Parliament's bureau called on South Sudan to "heed the voice of reason" and immediately pull its forces out of the areas it had occupied inside Sudanese territory, including Heglig.[96] On 26 April, the Arab League escalated its rhetoric, condemning South Sudan's "aggression" and saying Heglig belongs to Sudan. The Arab League went further to say it supported Sudan's "right to defend itself", and condemned South Sudan's alleged support of rebels in Sudan.[91] [...] - ^ "Yemen condemns South Sudan occupation of Heglig".
