Protester who exposed lies at the heart of Syria's regime

In most countries it would have been inconsequential. But for Ahmad Biasi, a young man from a small town in north-west Syria, the simple act of filming himself in his home town captivated the Syrian protest movement, made him a symbol of the nationwide insurrection – and may have put his life in danger.

It began when he was filmed in a video uploaded onto YouTube last month. Just days before, another film had been broadcast on news networks around the world, purportedly showing Kalashnikov-waving security forces beating and stamping on prisoners who had been captured in the town of Al-Bayda, close to Banias in north-western Syria. Ahmad Biasi had been among those being beaten and kicked by gun-toting security men in the original video.

The government responded by saying the video had been faked, that the uniforms of the security men were not right, and that the film had probably been shot in Iraqi Kurdistan.

Presumably incensed by the lie, Ahmad Biasi set out to prove that forces loyal to President Bashar al-Assad had been as brutal as the video seemed to show. Using a mobile phone, he and his friends shot a long sequence of film which started by driving past the entry sign to Al-Bayda and continued with footage from the clearly recognisable town square where all the prisoners were held and beaten.

In an amazing act of bravery – an act which has amassed him a devoted Facebook following – he finished the video by standing in front of the camera and holding up his national ID card, thus proving to the world that he was the Syrian national in the original video.

But his bravery came at a terrible cost. Earlier this month, Ahmad was arrested by one of Syria's most feared intelligence units. Human-rights activists – who received reports last week that he had died under torture – told The Independent that had been held in a secret-service headquarters in Damascus.

Before the weekend started, many people in Syria thought that Ahmad Biasi was dead. Human-rights organisations were receiving reports that he had suffered a terrifying final few hours at the hands of Syria's secret police.

By Saturday night, it transpired he was very much alive and had given an interview to state television offering proof to that effect. "We know he was detained and taken by security," said Wissam Tarif, executive director of the Syrian human-rights organisation Insan. "He was humiliated in front of other prisoners. They urinated on him and he lost consciousness after being electrocuted. He was very badly tortured. They made him an example to the others and made other prisoners watch as he was being tortured."

According to Mr Tarif, the types of abuse used by the Air Force Intelligence Directorate – the notorious branch of the secret police believed to have taken Ahmad – include electrocution, nail extraction and genital mutilation. "The level of brutality they are using is just absurd," Mr Tarif added. "It is so inhuman."

Other human-rights organisations also received reports of Ahmad's death. According to the Syrian Observatory for Human Rights, residents in Al-Bayda had feared that "Ahmad may have died after being subjected to severe torture".

Then on Saturday night, possibly under pressure from the growing publicity surrounding his case, Syrian state television dropped a happy bombshell. It ran an interview showing Ahmad Biasi sitting on a leather chair in a blank room expressing his "surprise" at hearing about his own death.

Looking gaunt but otherwise healthy, he said: "I was home when I heard that I had died under torture in a prison. I was very surprised and I felt strange when I saw it on the news. I wondered how they broadcast such fake news. It is humiliating."

Yet in spite of the dramatic turn of events, news of Ahmad's fate may turn out to harm the Syrian regime more than it had anticipated when it released the footage. Activists have already accused the secret police of extracting a forced confession, while others are saying that the interview has inadvertently done what Ahmad intended to do in the first place: prove that he was Syrian and that the original video of government abuse did not take place in Iraq.

"He is now a hero of truth for protesters," said a Syrian journalist from a small town outside Damascus. "The thing is that national television has proved that this video took a place in Syria. They proved how stupid they are."

His plight is also gaining online attention from growing numbers of people inside and outside Syria who view the activist's case as something of a cause célèbre – a rallying point for a nation in tumult.

Thousands of people have joined Facebook pages which have been set up in solidarity with Ahmad, while his case has attracted a small but growing following on Twitter.

Despite saying earlier in the year that he thought his country was impervious to the revolts shaking the Arab world, President Bashar al-Assad is now battling to contain a nationwide insurrection which began in the southern city of Deraa and has since spread to other major cities.

On Saturday, at least 11 people were killed in Homs when security forces opened fire on a funeral. The violence came a day after 44 people were killed in demonstrations around the country, according to the Syrian National Organisation for Human Rights. Rights groups say 850 activists have died and many thousands have been arrested and tortured since the uprising began.

How Ahmad Biasi showed Assad's brutality to the world

After the Syrian authorities dismissed video footage of security forces beating protesters they were holding captive (pictures 1 and 2) as fake, one of the men attacked, Ahmad Biasi (sitting on a step in picture 3), decided to prove them wrong.

He appeared on camera (picture 4) in another video, brandishing his ID card to prove he was Syrian (picture 5), and that the film had not been recorded in Iraqi Kurdistan, as the authorities had claimed. He began the footage by filming a sign (picture 6) bearing the town's name, al-Bayda, and then headed to the same spot featured in the original film (picture 7), recording his journey continuously.
