JUBA/MALAKAL (Reuters) - There are reports that South Sudan's warring factions are arming themselves for another bout of fighting, a delegation from the U.N. Security Council said on Tuesday, threatening both sides with sanctions amid growing fears of a man-made famine.

At least 10,000 people have been killed since fierce fighting erupted in December, pitting President Salva Kiir's government forces against supporters of Riek Machar, his former deputy and longtime rival.
