Violence in Sudan as it prepares to separate into two

After 21 years of civil war, South Sudan is finally gaining independence and will become its own country on 9 July.

But tensions are still rising between the north and those who support the south.

Some of the worst violence is happening in a place called South Kordofan.

It's hard to find out exactly what's happening as the area has been virtually cut off by the military.

But aid workers who've been in Sudan say there have been daily bomb attacks by government forces from the north, and people live in constant fear, so tens of thousands of people are on the move trying to escape.

International leaders like US President Barack Obama are calling for a ceasefire and talks are happening in Ethiopia to try and stop the violence, but nobody knows whether they will work.
