Charles Taylor
The newly appointed prosecutor for Sierra Leone's special tribunal has pledged to bring former Liberian leader Charles Taylor to trial on war crimes charges.

Calling Taylor a "monster of evil," Desmond de Silva also renewed a call for Nigeria to turn the exiled former president over to the United Nations-backed court.

Mr. Taylor has been indicted on charges that he backed Sierra Leone's notoriously brutal rebel movement in exchange for diamonds.

Mr. De Silva will officially take over as the tribunal's lead prosecutor when David Crane leaves the post in July.

The war crimes court was set up to try those most responsible for human rights abuses committed during Sierra Leone's decade-long civil war.
