The African Union called on Wednesday for a speedy trial for those responsible for the killing of school children who protested in the Sudanese city of El-Obeid on Monday. Mohamed Hassan Lebatt, the bloc's mediator in Sudan, also called for the ruling military council and opposition coalition to sign a constitutional declaration they have been wrangling over for weeks. Lebatt told a news conference a joint legal committee has almost completed its work on the document. Source: Reuters
