A man has died and two others have been injured in a knife and hammer attack in Paris.
It's understood the victim was a German national who was among a group of tourists targeted not far from the Eiffel Tower.
Following the incident, the assailant was chased by police before being tasered and arrested.
French Interior Minister Gerald Darmanin said the Paris attack is believed to be terror-related.

Mr Darmanin said the attacker had shouted "Allahu Akbar" (God is great) and told police he was upset because "so many Muslims are dying in Afghanistan and in Palestine".
France has been under a heightened terror alert since the fatal stabbing in October of a teacher in the northern city of Arras by a former student originally from the Ingushetia region in Russia's Caucasus Mountains.
