Here is a look at some of the stories that CNN plans to follow this week:
War crimes sentence expected for former Liberia leader
The first former head of state to be convicted of war crimes since World War II is expected to be sentenced Wednesday.
Charles Taylor, who was president of Liberia from 1997 to 2003, was convicted last month of aiding rebels in neighboring Sierra Leone in a campaign of terror that involved murder, rape, sexual slavery and conscripting children younger than 15.
There is no death penalty in international criminal law, and Taylor, 64, would serve out any sentence in a British prison.
Last month's ruling by the international tribunal was the first war crimes conviction of a former head of state by an international court since the Nuremberg trials after World War II that convicted Adm. Karl Doenitz, who became president of Germany briefly after Adolf Hitler's suicide. Former Yugoslav President Slobodan Milosevic was tried by an international tribunal, but he died before a judgment was issued.
Earlier this month, Taylor said he was wrongly portrayed, and that he tried to bring peace to Sierra Leone. He said his trial was corrupted by money, and that witnesses were paid off.
Will WikiLeaks founder be extradited to Sweden?
Britain's Supreme Court is expected to rule Wednesday on whether WikiLeaks founder Julian Assange should be sent to Sweden to face allegations of rape and sexual assault lodged by two women.
WikiLeaks, which facilitates the anonymous leaking of secret information, gained global fame in 2010 with the leaks of documents relating to the Iraq and Afghanistan wars, and then followed up by leaking nearly a quarter million State Department cables. Â A U.S. Army intelligence analyst is facing charges on suspicion of leakingÂ hundreds of thousands of classified military and State Department documents to WikiLeaks.
Assange has repeatedly denied the rape and sexual assault allegations. While fighting extradition, Assange has been under house arrest in Britain since December 2010. He recently started a talk show that he runs from Britain but airs on a Russian television network.
