Two people have been killed and five wounded in a knife attack in south-east France, in what the interior minister called a terrorist incident. Witnesses said the attacker entered a tobacconist in the town of Romans-sur-Isère, near Grenoble, and stabbed the owners and a customer. He attacked more people at two other shops before being arrested. Prosecutors said the suspect was a Sudanese refugee in his 30s who lived in the town. At the time of his arrest, the man was "found on his knees on the pavement praying in Arabic", prosecutors said. David Olivier Reverdy, of the National Police Alliance union, said the man had asked police to kill him. Counter-terrorism prosecutors said they had launched an investigation into "murder linked to a terrorist enterprise". The suspect was not previously known to the police or intelligence services, news website France Bleu reported. On a visit to the town, Interior Minister Christophe Castaner said: "This morning, a man embarked on a terrorist journey."//BBC
