Paris: French police on Tuesday shot and seriously wounded an unarmed woman who was making threats at a train station in Paris during morning rush hour, police and prosecutors told told AFP.

According to witnesses the woman, who was completely veiled, 'made threats', a police source said, adding that 'police fired because they feared for their safety'.

After passengers on a suburban train alerted police, agents managed to 'isolate' the woman at the Bibliotheque Francois Mitterrand station on the capital's south bank which was evacuated, the source said.

She 'refused to follow police orders' and threatened 'to blow herself up', the Paris prosecutor's office said.

A police officer then fired a single shot, inflicting a life-threatening injury to her abdomen, it said.

No explosives or other arms were found on the woman, the police source said.

Police have launched two investigations, prosecutors said. One will probe the woman's actions, while another is to elucidate whether the police's use of a firearm was justified.

France has been under 'attack alert' since October 13, when a teacher in the northern city of Arras was stabbed to death by a former pupil.

Bomb alerts have led to the evacuation of dozens of airports, train stations and tourist sites in recent weeks.
