The suspect had in 2016 been sentenced to four years in prison for planning another attack, and had been on the French security services’ watch list, the minister said, adding that he was also known for having psychiatric disorders.
The man attacked a tourist couple at around 1900 GMT with a knife on the Quai de Grenelle, a few feet away from the Eiffel Tower, mortally wounding the German national. He was then chased by police and attacked two other people with a hammer, including the Briton, before being arrested.
The suspect had shouted out “Allahu akbar” and told police he was upset because “so many Muslims are dying in Afghanistan and in Palestine” and was also upset about the Gaza situation, Darmanin said. French anti-terrorism prosecutors are leading an investigation into the incident. Police sources confirmed the attacker had posted a video on social media at the moment of the attack, claiming responsibility.
