France marked the fourth anniversary of the Paris attacks with a remembrance ceremony attended by the country's interior minister, Christophe Castaner, and the city's mayor, Anne Hidalgo.

On 13 November 2015, Paris suffered the biggest loss of life on French soil since World War II, after coordinated terror strikes killed 130 people and injured 350.

A special ceremony was held in front of the Bataclan theater, where 90 people died when gunmen opened fire during a live show. Floral tributes were left in front of the concert hall and a plaque with names of the victims was unveiled.

Paris authorities have also announced plans to set up a garden of remembrance to "keep the memory of the victims alive." Discussions over the project have been held with the victims' families and survivor groups including Life for Paris and 13 Eleven 15. 

An investigation into the attacks that concluded in October, led to 11 indictments and 14 pre-trial arrests. A date for the hearings has not been declared.

Most of the perpetrators involved were killed during the attacks or in police raids in the days that followed. Two suspects were later arrested in Brussels in March and April 2016.

The trial, is not expected to commence until next year or even 2021 and could potentially last for six months, according to French news sources. 

The anniversary comes just weeks after survivors of the attacks wrote an open letter in the Le Parisian newspaper, calling on France and other Western nations to support Kurdish forces in Syria, following the US military withdrawal.
