An Afghan man seeking asylum was arrested after a 19-year-old was killed and nine others wounded in a knife attack at a subway stop near Lyon, France, Saturday. Three of the victims are in critical condition.

A suspect carrying a knife was arrested. Citing a national police official, The Associated Press reported that the man was a 33-year-old Afghan citizen who had applied for asylum in France and was awaiting a response.

Officials said the attack, which took place in Villeurbanne, a suburb of Lyon in the southeastern part of France, was not terrorism related.

French authorities have made no official comment about the assault. Local police told the AP it was unclear if the victim knew the man who killed him.

France saw a series of knife attacks last year.

In September, a man wielding a knife at a French movie theater stabbed two people after a fight broke out in the northern town of Rennes.

A week earlier, seven people, including two British tourists, were injured when a man went on a rampage with a knife and an iron bar in northeastern Paris. The assault came after a series of knife attacks in France.

While terrorism was ruled out for those two attacks, ISIS claimed responsibility for another attack two weeks before that, when a man killed two people with a knife before he was killed by police in the town of Trappes, west of Paris.

The motive for Saturday’s attack was unclear, police said. Cops called off a search for second suspect.
