The United Nations Security Council has voted unanimously to authorise a
10,000-strong peacekeeping force for southern Sudan but remains deadlocked on any action for Darfur in the west.
The peacekeepers are to monitor a crucial agreement signed in January between the Khartoum government and southern rebels that ended a 21-year old civil war.
The conflict has cost 2 million lives and forced 4 million people from their homes.
