Paris police shoot man armed with knife at rail station

French police have shot and wounded a knife-wielding man at Paris' Montparnasse train station, the Paris prosecutor's office says.

An officer used his "weapon" on the man, who then inflicted knife wounds on himself, the prosecutor's office said in a statement.

A police source said the man had threatened his wife and children in a Paris suburb before taking a train destined for Montparnasse where police were waiting for him.

When officers confronted the man, he threatened to kill himself and was then shot in the legs, the source said.

The prosecutor's office said at least one gunshot was heard.

One witness told Reuters they heard several shots.

A Reuters photographer at the station when the incident occurred said the police intervention caused a crowd surge through the concourse.
