There are questions about Colonel Gaddafi's final moments after conflicting reports about how he died.
Libya's new government, the National Transitional Council, said he'd been caught in the crossfire between rebel and loyalist fighters while being taking to hospital.
However, at the scene of the dictator's death in his hometown of Sirte yesterday, one rebel said he'd been captured alive and shot.
One anti-Gaddafi fighter said: "We catch him there (in a sewerage pipe) and we shot him. Somebody shot him by gun."
Both Gaddafi and his son Saif al-Islam were wanted by the International Criminal Court for crimes against humanity for planning a violent suppression of the uprising in Libya.
A summary execution such as the one described yesterday would anger some parts of the international community who wanted to see him stand trial at the Hague.
