South Sudan rebels accuse army of violating ceasefire

South Sudan rebels on Sunday accused the army of violating a ceasefire, just hours after it came into effect, by bombarding their positions along the White Nile river.

"A military convoy -- two barges, seven gunboats -- has been moving from Bor to Panijar. Whenever they see our positions on the banks, they shell," said rebel spokesman Dickson Gatluak.
