PARIS • A man wielding a knife and an iron bar injured seven people, including three tourists, in Paris, in an attack that bystanders tried to stop by throwing petanque balls at the assailant.
Four of the victims were in a critical condition, police said, after the man, believed to be an Afghan national, went on the rampage next to a canal in the north-east of the capital on Sunday evening.
Two British tourists, an Egyptian tourist and a local man were among the injured, police added.
The suspect, believed to be in his 30s, had been overpowered by bystanders and was unconscious when officers arrived on the scene and took him to hospital, police said.
A source close to the inquiry added that though he had targeted foreigners, "nothing at this stage suggests a terrorist attack".
Chaos erupted on the banks of the Bassin de la Villette, an area popular with locals and visitors, who frequent the cafes, cinemas and other cultural venues along its banks, just after 11pm local time.
Eyewitness Youssef Najah, 28, said he was walking beside the canal when he saw a man running and holding a knife about 25-30cm long.
"There were around 20 people chasing him. They started throwing petanque balls at him," Mr Najah said, referring to the sport popular in France also known as boules.
"Around four or five balls hit him in the head, but they weren't able to stop him," he added.
According to the same witness, the attacker then dived into an alleyway, where the man "tried to hide behind two British tourists. We said to them: 'Watch out, he has a knife.' But they didn't react". The pair, said by police to be in their 50s, were then attacked, he said.
A security guard at one of two cinemas there said he had seen the attacker running away from two men who were trying 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 Agence France-Presse.
An Algerian man identified as Smain told Le Parisien newspaper he was part of a group that apprehended the attacker.
"I managed to jump on him and throw him to the ground and get his weapon off him," he said. He added that the attacker sustained "several blows from petanque balls, iron bars and sticks" and "looked drugged".
The UK foreign office said it was aware of reports of the attack and was "urgently investigating this incident" in cooperation with French authorities, British media reported.
Interior Minister Gerard Collomb in a statement praised those who intervened to stop the attack for their "responsiveness and courage".
A police investigation has been launched for attempted murder, according to a judicial source.
It is the latest of several knife attacks France has seen in recent weeks.
On Aug 23, a man stabbed his mother and sister to death and seriously injured another person in a town near Paris before being shot dead by police. The authorities said the 36-year-old had serious mental health problems and had been on a terror watch list since 2016.
That attack came days after an Afghan asylum seeker was arrested in the south-western town of Perigueux for a drunken rampage with a knife in which four people were wounded.
Police said investigators had "very quickly" dismissed a terrorist motive after the Aug 13 incident.
And on June 17, two people were hurt in another southern town when a woman attacked them in a supermarket with a boxcutter knife.
France has been on high alert following a string of terror attacks in recent years.
