In a statement given out to a France-based Europe1 radio station, lawyer Marcel Ceccaldi stated, "NATO helicopters opened fire on (Gaddafi's) convoy. This convoy did not pose any threat to civilians. It was an operation to eliminate the Libyan leader, planned by the North Atlantic alliance."
The lawyer also slammed the move to display Gaddafi's dead body at a shopping centre in Misrata for four days.
Gaddafi faced a brutal end to his life after being captured alive by National Transitional Council fighters near his hometown Sirte on Oct 20. He ruled oil-rich Libya with an iron-fist for close to 42 years. The UN human rights office as well as Russia and the US have called for a probe into Gaddafi's killing.
