A new trial has begun in the case of Guus Kouwenhoven, the Dutch businessman accused of international arms trafficking.

Kouwenhoven was convicted in 2006 of illegal arms shipments to Liberia. That judgment was overturned on appeal, but the Dutch Supreme Court ruled that the appeal process must be repeated.

One of the witnesses expected to appear this time is former Liberian president Charles Taylor, who is on trial in the Netherlands for war crimes and crimes against humanity.
