Saro-Wiwa memorial art bus impounded by Nigeria

A bus created as an artistic memorial to commemorate the 20th anniversary since the hanging of environmentalist Ken Saro-Wiwa was impounded by the Nigerian Government.
Tuesday marks 20 years since the execution of Saro-Wiwa and eight other Nigerian human rights activists by Nigeria's then-military government.
They had led protests against environmental damage in the oil-rich Niger Delta region caused by oil giant Shell. They were hanged, despite an international outcry, for their alleged involvement in the murder of four Ogoni tribal leaders.
