The knifeman who killed one man and wounded four other people on Saturday night in Paris had been on an anti-terror watchlist of suspected extremists, said sources close to the inquiry on Sunday.

The Frenchman, born in 1997 in the Russian republic of Chechnya, was on the so-called "S file" of people suspected of radicalised views who could pose security risks, the sources said, though he did not have a criminal record. Police shot and killed the man shortly after being alerted to the attack on the Rue Monsigny. His parents have been taken into custody. Investigators have not yet said when the man arrived in France.
