Muammar Gaddafi is dead after being seriously wounded when captured, Thursday near Sirte, Libya, according to GlobalPost sources in Sirte and officials with the Libyan National Transitional Council (NTC).
There are multiple reports that Gaddafi's body has been taken to a secret location in Misrata, about 125 miles to the west of Sirte.
"Gaddafi's body is with our unit in a car and we are taking the body to a secret place for security reasons," an NTC official told Reuters.
Gaddafi's body is now in Misrata and being kept in a mosque, Al Jazeera says.
Al Jazeera has shown an image that appears to be of Gaddafi's body, from a video the television network said it had acquired.
"We announce to the world that Gaddafi has been killed at the hands of the revolution," NTC spokesman Abdel Hafez Ghoga said, Agence France-Presse reports.
"It is an historic moment. It is the end of tyranny and dictatorship. Gaddafi has met his fate," he said.
Libya's prime minister has also confirmed Gaddafi's death.
Sources in Sirte told GlobalPost correspondent James Foley that Gaddafi had been mortally wounded while being captured, and the former Libyan leader died in the ambulance.
Rebel fighter Imad Moustaf, who claimed to be an eyewitness to Gaddafi's capture, said he saw Gaddafi with serious wounds to the head and near to his heart.
