A German tourist died and two other people, including a British citizen, were hurt after an attack by a man armed with a knife and a hammer near the Eiffel Tower in Paris on Saturday, in what President Emmanuel Macron described as "a terrorist attack".
Police quickly arrested the 26-year-old man, a French national, after subduing him with a Taser stun gun, Interior Minister Gerald Darmanin told reporters on Saturday.
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.
The man attacked a tourist couple at around 1900 GMT (23:00 UAE time) 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, before being arrested.
"We are supporting a British man who was injured in Paris and are in contact with the local authorities,” a spokesperson for the British foreign ministry said.
French anti-terrorism prosecutors are leading an investigation into the incident.
"I send all my condolences to the family and loved ones of the German national who died this evening during the terrorist attack in Paris and think with emotion of the people currently injured and in care," President Macron said on the social network platform X.
Prime Minister Elisabeth Borne expressed defiance in the face of such attacks, saying on X: "We will not give in to terrorism."
