The extraordinary trial of the ten men accused of being directly or indirectly involved in the March 2016 Brussels terrorist attacks, is set to begin on December 5.

The trial which was due to start in October this year, was delayed after a preliminary hearing in September at Belgium's Court of Assizes — the court which deals with the country's deadliest criminal cases — ended with defense lawyers saying that they cannot proceed with the case if their clients had to speak through glass cubicles at court. 

Jamila Adda, President of the Life4Brussels association — an organization which was set up a day after the attack to support victims and their families, told DW that the repeated delay in the lawsuit has "totally weakened victims' morale."

"It’s been six years since the attacks and victims and their families feel abandoned by the Belgian State. They are also very stressed. I was on the phone with a woman who was at Belgium's Zaventum Airport on the day of the attack with her husband, who told me how her husband continues having nightmares from that day," she said, adding that the wait for justice has been painful for them. 

Terrorist attacks paralyzed Brussels

On the fateful morning of March 22, 2016, three coordinated suicide bombings in Brussels killed 32 people and paralyzed the city. The first attack took place at Brussels international airport, killing 16 people. Just over an hour later, another blast occurred in the Maelbeek metro station, located near the EU institutions, killing another 16 people.

Three perpetrators were killed and more than 340 were injured in the blasts.

The so-called Islamic State (IS) terrorist group claimed responsibility for the attacks, with the defendants including a French citizen who was also involved in the Paris 2015 terrorist attacks.

Walking in front of the memorial dedicated to victims of the attacks at the subway station, Christelle Giovannetti, a French national based in Brussels who survived the attacks, recollected the trauma she experienced on the day of the bombs went off.

"I don't usually take public transport and that morning, even though I had read about what happened at Brussels airport, I decided to take the metro since I had a meeting in the city center," she said. 

"Suddenly, a bomb exploded in the metro and I knew we were under attack. Everything was pitch black and for a few seconds I couldn't see anything around me. I realized I also couldn't hear anything. The bomb was so loud, it had affected my ears.

"I still wear hearing aids even now and suffer a lot of ear problems. It's a lesser evil compared to what other victims experienced but it is hard for me to forget the ordeal of that day," she said, looking teary-eyed.

Among those killed at Maelbeek station was Sabrina Esmael Fazal. Her father, Hussein Esmael Fazal, told DW that his family is still trying to come to terms with the death of Sabrina, who was 22-years old when she died in the blast. 

Standing at Sabrina's grave in the Belgian city of Ottignies-Louvain-la-Neuve, Esmael Fazal talked of how his daughter was always cheerful. Losing her completely shattered his family, he said.

"For four years after the attack, I remained strong for the sake of my wife and family. But I've become very depressed in the past two years. I used to be a tram driver .. but I started getting panic attacks after my daughter's death and so now I've started working on the administration side of things," he said. 

Like Esmael Fazal, many victims' families still need ongoing psychological support. Life4Brussels, which was set up a day after the attacks to support victims, has been helping many of them.

Adda, added that the association holds regular meet ups for those affected by the bombings.

"When victims meet each other, they understand that what they're going through is totally normal and that they're not alone," she told DW.

"We've also set up legal hotlines for them to seek help. Many of them aren't even aware of their rights so we've set up a collective of lawyers who represent around 250 victims and help them understand their rights, for no legal fee," she said.

Extraordinary trial

Brussels-based criminal lawyer Olivia Venet is a part of this collective and will be representing the victims in the upcoming trial.

The case was uniquely complicated, she said, which is why it has taken so long to come to trial. 

"This case involved victims from different countries and the attackers also had different nationalities," she said. "We had to take our time making inquiries, going over multiple sources of proof and also collecting witness records. This long process of research is important to get justice."

Victim identification was also a big issue, and it took time to complete the genetic inquiries, she explained.

Speaking on the sixth anniversary of the attacks, Belgium's Flemish Minister of Justice, Zuhal Demir, said that the government "wants to ensure that the victims aren't alone" when the trial begins.

The verdict isn't expected until sometime next year. For many of the victims, seeing justice done, however long it takes, is critical for healing.

"It will still take me time to forget all the images from that day," said Christelle Giovannetti. "But the answers from the trial will help me better deal with my trauma and I hope to be able to move on with my life."
