ADDIS ABABA (AFP) - South Sudan's government and rebel forces face possible sanctions if they fail to progress with peace talks and stick to a ceasefire deal, United States and European Union envoys warned Wednesday.

The European Union "stands ready to consider targeted restricted measures against individuals obstructing the political process," EU envoy Alexander Rondos told reporters, speaking alongside US envoy Donald Booth, who said Washington was also "considering what measures might be taken."
