The 26-year-old suspect, a French national, was swiftly apprehended by police using a Taser stun gun, Darmanin informed reporters.
The suspect had previously been sentenced to four years in prison in 2016 for planning another attack and was on the watch list of French security services. Additionally, he was known to have psychiatric disorders, the interior minister added.
The incident occurred at approximately 7:00 PM GMT when the assailant targeted a tourist couple with a knife on the Quai de Grenelle, just a short distance from the iconic Eiffel Tower. Tragically, a German national was fatally wounded. The suspect then fled, pursued by police, and proceeded to attack two more individuals with a hammer before being apprehended.
During the attack, the suspect shouted "Allahu Akbar" (God is greatest) and expressed his frustration to the police, citing the loss of Muslim lives in Afghanistan and Palestine, as well as the situation in Gaza, according to Darmanin.
The investigation into the incident has been taken over by the anti-terrorism prosecutor's office.
This incident, which occurred on Saturday night in central Paris, raises concerns about security ahead of the upcoming Olympic Games, which are set to be held in the French capital in less than eight months.
The city has planned an unprecedented opening ceremony on the Seine river, expected to attract up to 600,000 spectators. The incident may prompt a reevaluation of security measures for the global sporting event.
