Opponents say there have always been questions over Gen Younes' loyalties The head of the Libyan rebel armed forces, Gen Abdel Fatah Younes, has been shot and killed by unknown assailants.He was gunned down on his way to answer questions about the lack of military momentum by the opposition, but reports say he was suspected of having ties to the forces of Col Muammar Gaddafi.
Gen Younes was a lifelong Gaddafi loyalist, helping the Libyan leader seize power in a coup in 1969.
As the former head of the country's Special Forces and the sitting interior minister he was the highest profile defector to the new rebel council in Benghazi and was rapidly appointed as the chief of the rebel armed forces.
But suspicions lingered about his true allegiance, fed by claims in Tripoli that there was someone on the ruling council who was in effect a double-agent.
According to the New York Times, Col Gaddafi's daughter Aisha rather mischievously refused to rule out the name of Gen Younes as the culprit in an interview she gave in April.
But it was also the lack of momentum on the battlefield and the inexplicable bit-part played by Special Forces defectors who should have had more of a leading role on the frontline that also nurtured doubts.
Some rebel fighters refused to take orders from him, giving their loyalty instead to the general's rival, the rebel commander Khalifa Hifter, who could well be named to succeed his now dead adversary.
Gaddafi contacts?Publicly Gen Younes was recalled for questioning about military operations, but there are allegations he was suspected of maintaining contacts with the Gaddafi regime.
So who killed him? Disgruntled rebel fighters, rivals looking for power or Gaddafi loyalists?
Although an arrest has been made, no names or motives have been made public and the circumstances surrounding the bodies remains unclear.

If you are sitting in Tripoli this must be manna from heaven.
But if you are in Benghazi this is awful timing for a movement continually struggling to gain momentum on the battlefield.
And it could hardly be worse for those governments (Britain being the latest) who have staked their diplomatic credibility on the rebel government in Benghazi.
Tribal divisionsWhat matters now is the impact this has. The death taps into tribal divisions within the opposition and some members of the general's Obeidi tribe are already armed and angry at what has happened.
Just when the rebels are desperate to drive forwards on the battlefield it leaves them without a leader. And for those countries like Britain that have officially recognised the National Transitional Council as the legitimate government of Libya it feeds serious doubts and concerns about the rebels' ability to end this conflict and their ability to function as a cohesive government.
One of the main criticisms of the Nato-led operation is that it was hastily conceived without a clear strategy or exit-route. Nothing that has happened this week will allay those fears.
But the hatred of Col Gaddafi and the craving to see him overthrown may be strong enough to keep this disparate and often shambolic rebel alliance together.
No Plan BFor many, like Nadia Darrez, a young lawyer in Misrata, people have sacrificed too much and there is no going back, no Plan B.
She has been sifting through what remains of her family home on Tripoli Street, an address synonymous with the ferocious battle that took place in the city. The flat has been devastated; great holes have been punched through the walls and ceiling, the floor is littered with broken glass, masonry and bullets.
Nadia was born here. She had four brothers when this battle began. One was killed by Col Gaddafi's men. The other three are now volunteer soldiers of the rebel army.
There is little left here but anger, grief and a desire for justice.
"We need our fighters to capture him [Col Gaddafi] and all those around him and we're not going to stop this fight until this happens," she says.
What is unclear is whether that unity of purpose is enough to allow the rebels to prevail or even keep them united.
The West is frustrated by the slow progress of this conflict and whatever the facts about the mysterious death of Abdel Fatah Younes, it will give Britain and the rest of the Nato-led alliance little confidence that this five-month old conflict will end quickly or cleanly.

Hama has seen some of the biggest protests yet Syrian tanks have stormed the northern city of Hama, killing at least 45 civilians, a leading rights group says.
Syria's anti-government protests, inspired by events in Tunisia and Egypt, first erupted in mid-March after the arrest of a group of teenagers who spray-painted a revolutionary slogan on a wall. The protests soon spread, and human rights activists and opposition groups say 1,700 people have died in the turmoil, while thousands more have been injured.
Although the arrest of the teenagers in the southern city of Deraa first prompted people to take to the streets, unrest has since spread to other areas, including Hama, Homs, Latakia, Jisr al-Shughour and Baniyas. Demonstrators are demanding greater freedom, an end to corruption, and, increasingly, the ousting of President Bashar al-Assad.
President Assad's government has responded to the protests with overwhelming military force, sending tanks and troops into at least nine towns and cities. In Deraa and Homs - where protests have persisted ? amateur video footage shows tanks firing on unarmed protesters, while snipers have been seen shooting at residents venturing outside their homes.
Some of the bloodiest events have taken place in the northern town of Jisr al-Shughour. In early June, officials claimed 120 security personnel were killed by armed gangs, however protesters said the dead were shot by troops for refusing to kill demonstrators. As the military moved to take control of the town, thousands fled to neighbouring Turkey, taking refuge in camps.
Although the major cities of Damascus and Aleppo have seen pockets of unrest and some protests, it has not been widespread - due partly to a heavy security presence. There have been rallies in the capital - one with an enormous Syrian flag - in support of President Assad, who still receives the backing of many in Syria's middle class, business elite and minority groups.
The Assad family has been in power for 40 years, with Bashar al-Assad inheriting office in 2000. The president has opened up the economy, but has continued to jail critics and control the media. He is from the minority Alawite sect - an offshoot of Shia Islam ? but the country's 20 million people are mainly Sunni. The biggest protests have been in Sunni-majority areas.
Although the US and EU have condemned the violence and imposed sanctions, the UN Security Council has been unable to agree on a response. Some fear the country could descend into civil war if the government collapsed, while others believe chaos in Syria ? with its strategic location and its web of regional alliances - could destabilise the entire Middle East.BACK {current} of {total} NEXT
