“French police have detained a man who stabbed seven people, injuring four seriously, in an attack on tourists and passers-by in Paris. The man, wielding a knife and iron bar, struck just before 23:00 (21:00 GMT) by a canal in Paris’s 19th district. People playing pétanque – a French bowling game – threw metal balls at the attacker, and he was overpowered. The man, said to be Afghan, was soon arrested. The incident is currently not being treated as a terrorist attack.”
