A man has been arrested in connection with an attack in Paris last night, in which seven people were injured.
Two British tourists were among the injured, after the man carried out the attack with a knife and an iron bar.
Four of the victims are said to have suffered severe wounds.
French police have said that there was no initial indication that the attack was linked to terrorism.
It is understood that the man who was arrested is an Afghan national.
"Nothing at this stage shows signs of a terrorist nature in these assaults," sources told AFP, adding that the attacker had targeted "strangers in the street".

The incident took place just after 11pm local time, on the banks of a canal in the northeast of the capital.
A security guard at one of two cinemas on either side of the Canal de l'Ourcq said he saw a man who had already assaulted people being chased by two other men who tried to stop him.
"He had an iron bar in his hand which he threw at the men chasing him, then he took out a knife," he told AFP.
A police investigation has been launched for attempted murder, according to a judicial source.
