"In memory of the injured and murdered victims of the attacks of November 13, 2015," Castex wrote in a series of tweets while attending the scenes of attacks.
Apart from Castex, other top officials including Interior Minister Gerald Darmanin, Justice Minister Eric Dupond-Moretti, Paris mayor Anne Hidalgo, and Saint-Denis mayor Mathieu Hanotin participated in commemoration services.
Earlier in November, the city administration cancelled mass memorial ceremonies over the terror acts that occurred on November 13, 2015, due to the worsening epidemiological situation and other Covid-19 restrictions.
Small groups of elected officials and members of associations of victims of the attacks all participated in Friday's services.
A series of coordinated Islamist attacks, which occurred in different parts of the French capital and its northern suburb of Saint-Denis in 2015, claimed a total of 130 lives with another 400 people reportedly injured.
