DUBAI: Forty-one civilians in all were murdered in a single coldblooded incident in 2013. One by one, the blindfolded detainees were brought to the edge of a freshly dug pit in the Damascus suburb of Tadamon and systematically shot. The bodies, piled one on top of the other, were later set on fire.

Footage of the massacre, carried out by Syrian militia members loyal to President Bashar Assad, emerged only in April this year following an expose by the UK’s Guardian newspaper and the online New Lines Magazine.

The amateur video, taken by the killers themselves, was discovered by a militia recruit in the laptop of one of his seniors. Sickened by what he had seen, the rookie passed the video on to researchers, who later confronted one of the killers identified in the footage.

Journalists and activists from southern Damascus, speaking to Arab News following online circulation of the video, said that the Tadamon massacre was unlikely to have been the only atrocity committed in the area during that period.

Throughout 2012 and 2013, pro-regime militias would shoot random passers-by at checkpoints in Tadamon, Yalda and the Yarmouk camp, and also gun down people in their homes. Bodies of the victims were often left to rot, according to local residents.

“We would hear about these massacres and the burning of corpses,” Rami Al-Sayed, a photographer from the Tadamon neighborhood, told Arab News. “We knew that anyone arrested by the shabiha of Nisreen Street would be disappeared and, in most cases, executed.”

Shabiha is a Syrian term for militias sponsored by the Assad government that carried out extrajudicial killings during the civil war that broke out in the wake of the 2011 uprising.

Nisreen Street was notorious as a stronghold of one such militia, which at the start of the uprising violently repressed protests, and later began detaining and executing residents of southern Damascus.

“All the victims identified so far are not known to have participated in protests or military activity against the regime,” Al-Sayed said.

“In fact, the presence of a strong pro-regime contingent in Tadamon forced most people opposed to the regime to flee the neighborhood entirely, or to reside in an area that was still under the control of the opposition in 2013.”

Syrian human rights monitors say entire families that attempted to cross checkpoints in southern Damascus went missing in 2013, including children and the elderly. In many cases, their fate remains unknown even today.

These families constitute a small fraction of the 102,000 civilians who have vanished since the uprising began in 2011, according to the Syrian Network for Human Rights, which believes regime forces are responsible for the forced disappearance of almost 85 percent of the total number of missing Syrians.

Most of the victims of the Tadamon massacre are yet to be publicly identified since their families, fearing further reprisals, are reluctant to come forward and acknowledge their relationship.

“Many of the relatives are afraid to announce that they recognized their loved one in the video because they are afraid of persecution by the Syrian secret police, especially if they live in regime-held areas,” Mahmoud Zaghmout, a Syrian-Palestinian from Yarmouk camp, told Arab News.

Residents of southern Damascus expect neither the perpetrators of this specific massacre nor those responsible for overseeing countless others to be held to account any time soon, despite the incriminating video evidence.

“This is not the first time such clear evidence of the involvement of Syrian regime personnel in crimes of genocide has been exposed,” said Zaghmout. “But the regime remains protected by the Russians, enabling it to avoid any accountability.”

When footage of the massacre first emerged online, the families of Syrians and Palestinians who had disappeared in 2013 frantically scanned the video for clues to the whereabouts of their loved ones.

Even if the horrific images confirmed their worst fears, they thought, at least they might find a semblance of closure that would end the uncertainty concerning their loss and allow them to mourn properly.

Families endured the same trauma while trawling through thousands of photographs smuggled out of Syria by a military defector code-named Caesar in 2013. The images contained horrifying evidence of rape, torture and extrajudicial executions inside regime jails.

Evidence provided by Caesar was used to help prosecute Anwar Raslan, a former Syrian intelligence officer, who in January was sentenced to life in prison by a court in Germany for the horrific abuses he inflicted on detainees.

The Koblenz trial offered a glimmer of hope to Syrians eager to see their tormentors face justice. Despite this small victory, the Tadamon families doubt the militiamen who murdered their loved ones will ever have their day in court.

One couple who sat through the gruesome footage were the parents of Wassim Siyam, a Palestinian resident of the Yarmouk camp, who was 33 when he vanished.

 “I watched it a few times, then the way a man was running caught my attention. It was my son. It’s his way of running. I knew it was him,” Wassim’s father told journalists.

Many families had held out hope that their children might still be alive somewhere in the regime’s prison system and would someday be released under one of the government’s occasional amnesties.

On May 2, about 60 detainees were released by the regime under a new presidential decree granting amnesty to Syrians who had committed “terrorist crimes” — a term authorities often use for those arbitrarily arrested.

Some had spent more than a decade in facilities described by the rights monitor Amnesty International as “human slaughterhouses.”

Large crowds gathered in Damascus in the days following the amnesty, hoping to find their relatives. Some held photos of their missing loved ones and asked the freed detainees whether they had seen them alive in jail.

Wassim’s mother had long held out hope that her son might still be alive, almost a decade after his disappearance. “I kept my faith in God. I thought he was probably detained but still alive,” she was quoted as saying.

“I don’t know how they were able to do this to the civilians. One avoids even stepping on an ant while walking. How were they able to do this?”

She added: “The community loved my son. We never harmed anyone to be hurt this way. I expected to see him out of prison — meek, tortured, maybe missing an eye — but I did not expect this.”

The clip of the Tadamon massacre ruled out the possibility of Wassim and the other men being still alive.

“The hope that they had, even if a small one, was gone,” Hazem Youness, a Palestinian-Syrian researcher and former diplomat who has interviewed several of the families, told Arab News.

The daughters of one of the victims told Youness that since her father disappeared, “whenever I would hear a knock on the door, I hoped it would be my father, and now I can’t be hoping anymore.”

Aware of the brutal and subhuman conditions inside regime jails, some families admitted they were relieved to see their relatives in the video. At least, they reasoned, their loved ones had not suffered for long.

“It’s better this way,” said Youness, quoting one of the families. “We were reassured that he is not being tortured now. It was harder for us when we would keep thinking: ‘What is he doing? Is he being tortured now? What is he eating? How is his health? Is he sick? Where is he?’”

The release of the footage had another important effect: It validated the claims of survivors and confirmed that killings had indeed taken place in the area.

“Everyone knew massacres were happening,” said Youness. “People in Tadamon and the areas of the camp said that there was a smell of blood and then of rotting corpses coming out from houses.

“But, you know, it’s one thing to suspect something or know it; you still don’t want to believe it’s true, and then you have the proof.”

Some local residents were not surprised to learn that war crimes had been committed in Tadamon. Rather what they found shocking was the cruelty and inhumanity of the militiamen in the video.

“I didn’t expect it to be this horrific,” said Youness. “You can see from the video that it’s a normal thing for them. You see that they do this with ease, while joking around with each other, like it’s routine, like this is a game.

“These are beasts killing in cold blood. It’s unfair to call them beasts, because beasts have at least some degree of compassion and mercy.”

Alluding to the importance of staying optimistic, Youness said: “The path to justice, unfortunately, is a long one. But no matter how long it takes, the march must continue.”
