[LI5] What's happening in Sudan?

I've been hearing a lot about Sudan but don't really know what's going on. Can someone explain what's happening like I'm 5?

Sudan is a country in the northeast of Africa (just south of Egypt).  The country was mainly divided between different religious and ethnic groups.  The Muslim group in the north has been pretty much at war with nomadic tribal and Christian groups in the west and south for decades since the country became independent.  Many people have been killed and millions have had to leave their homes.  In the south, so many people were of the non-Muslim group that last year they had a vote to become a new country.  99% of them voted yes.  Last month, the south part of Sudan officially became a new country, South Sudan.  They are still fighting because there are oil piplines and the Nile river that run through both countries and are worth a lot of money.  Also, there is a region still in the west of Sudan called Darfur where a lot of the same conflicts are happening.  They have not become an independent country.
