A french court has found fourteen people guilty of being accomplices in a series of terrorist attacks that took place in Paris in 2015.

Eleven of the people convicted were in court for the verdicts, while the other three -including the only woman to face charges - were tried in absentia after leaving to join IS. 

Thirteen men and a woman were on trial over the 2015 attacks against the satirical newspaper Charlie Hebdo and a supermarket in Paris - that sparked a wave of violence by the so-called Islamic State group in Europe.

Seventeen people and all three gunmen died during the three days of attacks in January 2015 in the French capital.

Those on trial in France's terrorism court in Paris were accused of buying weapons, cars, and helping with logistics.,

The attacks from January 7-9 2015 started during an editorial meeting at Charlie Hebdo, whose offices had been unmarked and guarded by police since the publication of caricatures of the Prophet Muhammed years before.

Brothers Cherif and Said Kouachi gunned down 12 people before carjacking a vehicle and fleeing.

They claimed the attacks in the name of al-Qaida.

Two days later, on the eve of the Jewish Sabbath, Amedy Coulibaly stormed the Hyper Cacher supermarket, killing four hostages in the name of IS as the brothers took control of a printing office outside the French capital.

The attackers died that day during police raids.

It took days for investigators to realise that Coulibaly was also responsible for the seemingly random death of a young policewoman the previous day.

It took further weeks to unravel the network of petty criminals and neighbourhood friends linking the three attackers.

By then, Coulibaly's wife had left for Syria with the help of two brothers also charged in the case.

Most of the 11 who will appear in court insist their help in the mass killings was unwitting.

"Since 2012, terrorism capitalised on the prevailing delinquency there is around these terrorists," said Samia Maktouf, a lawyer for one of the attack survivors.

"They are not second fiddles, they are full accomplices. You know, when you provide a weapon it's not to go and party."

Later that year, a separate network of French and Belgian fighters for IS struck Paris again, this time killing 130 people in attacks at the Bataclan concert hall, the national stadium, and in bars and restaurants.

After the trial was delayed because of the coronavirus pandemic, those convicted today were all found guilty of helping to arrange, fund and support the terrorist attacks.
