The U.N. secretary-general is urging the president of South Sudan to meet his rival next week, even though the peace deal that promised the June 9 meeting fell apart within days. According to AP, Ban Ki-moon on Wednesday spoke by phone with President Salva Kiir and urged that all military operations end "immediately." A statement from Ban's office says the secretary-general expressed "grave concern" that fighting has continued in spite of peace deals reached in January and in May between Kiir and former vice-president Riek Machar. The latest peace deal committed Kiir and Machar to meet monthly.
