A high-level delegation of ministers from South Sudan has arrived in the Sudanese capital Khartoum to prepare for a key meeting between the presidents of the two countries, according to AP. Sudan's President Omar al-Bashir and his South Sudan counterpart, Salva Kiir, are to meet on April 3. It would be the second time the two hold talks since South Sudan became independent last year, after decades of civil war. The leaders are to meet in South Sudan's capital, Juba. Sudan's state news agency said Thursday that the South Sudanese delegation carried an official invitation for al-Bashir to come to Juba. The two nations have been at odds over oil and profits, and Sudan has accused its new neighbor of supporting militia fighters on its soil.
