( CNN ) -- The family of deceased Libyan strongman Moammar Gadhafi will file a war crimes complaint against NATO with the International Criminal Court , a lawyer representing the family said Thursday . Members of the family believe NATO 's actions led to Gadhafi 's death last week , said Marcel Ceccaldi . `` All of the events that have taken place since February 2011 and the murder of Gadhafi , all of this means we are totally in our right to call upon the International Criminal Court , '' Ceccaldi , a French attorney , said . NATO responded that it `` conducts its operation in strict conformity with the relevant U.N. Security Council resolutions . '' In a statement Thursday , a NATO official said , `` At no time during Operation Unified Protector has NATO targeted specific individuals . '' The ICC had previously issued a warrant for Gadhafi 's arrest , accusing him of crimes against humanity . The ICC still has warrants for the arrest of Gadhafi 's son , Saif al-Islam Gadhafi , and his brother-in-law Abdullah al-Sanussi . Questions surround the death of Moammar Gadhafi , who eluded forces loyal to the National Transitional Council for months . Video shows Gadhafi was alive when captured by the opposition . He died from a shot in the head , officials said , but the circumstances surrounding the shot remain unclear . The United States said it supports an independent investigation , as called for by the United Nations and by Libya 's new leadership . Ceccaldi said the Gadhafi family 's complaint will be filed in the coming days . `` Now we will wait and see if the ICC is a judicial system which is independent and impartial , '' he added . Lt. Gen. Charles Bouchard , commander of the NATO military operation , said earlier this week that NATO `` did not get involved in anything beyond what was our legal mandate and we remain well within the mandate assigned to us by the North Atlantic Council . '' While Gadhafi survived an airstrike in the Sirte area shortly before he died , Bouchard said NATO did not know the former Libyan leader was in the convoy . `` We saw a convoy , and in fact we had no idea that Gadhafi was on board , '' Bouchard said . Some vehicles in the convoy were carrying weaponry , and seemed to present a potential threat to the population , he said . The news came as the U.N. Security Council voted unanimously Thursday to end NATO 's military operations in Libya .
NEW : NATO responds that it never targeted specific individuals in the operation . The Gadhafi family blames NATO for Gadhafi 's death , the lawyer says . The family will file the complaint with the ICC , the lawyer says . The ICC had a warrant for Gadhafi 's arrest .
