Qaddafi was captured wounded, but alive Thursday in his hometown of Sirte. Bloody images of Qaddafi being taunted and beaten by his captors have raised questions about whether he was killed in crossfire, as suggested by government officials, or was executed.

Clinton tells NBC’s “Meet the Press” that she backs a proposal that the United Nations investigate Qaddafi’s death and that Libya’s Transitional National Council look into the circumstances, too.

Clinton says a democratic Libya should begin with the rule of law and accountability, as well as unity and reconciliation. She says investigating Qaddafi’s death is part of the process.
