The Nigerian government impounded a bus created
as an artistic memorial to commemorate the 20th
anniversary since the hanging of environmentalist
Ken Saro-Wiwa.
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.
