Chaos still reigns in Libya, a year after Gaddafi's death
Bani Walid conflict shows Libya has far to go as it tries to emerge from shadow of brutal dictator
"Nobody knows where Gaddafi is buried," said Abubaker Ali, 29, a volunteer with the forces massed at the Sufageen forward base in the Libyan desert.
Looking towards the horizon, where black smoke rose from the town of Bani Walid, he said: "He's buried in the desert. But nine-tenths of Libya is desert."
Muammar Gaddafi was captured and killed by rebels a year ago yesterday and buried somewhere under the rust-coloured sand. The location of the grave is a closely guarded secret. But in the same stretch of sand the same rebel forces - now wearing government uniforms - are preparing a final push into the last of his strongholds.
Bani Walid, 145 kilometres from Tripoli, was supposed to have fallen a year ago. Instead Gaddafi's former henchmen and officials have turned the town into a bastion.
The latest push yielded a significant arrest yesterday, with government forces capturing Gaddafi's ex-spokesman.
The urbane, English-speaking Moussa Ibrahim, who became the international face of the regime in its final months, was captured as he was trying to flee the town, according to the Libyan State News Agency.
The year since his death has been one of chaos and violence.
