A 16-year-old French girl has been charged with terror offences after allegedly inciting attacks on behalf of Islamic State. The girl was allegedly using a social media app to spread Isis' calls for violent attacks, the Paris prosecutor's office said.

She has been charged with "criminal conspiracy with terrorists", and "inciting to commit terrorist acts through an online communication medium".

The girl was described as "extremely radicalised," and was allegedly the administrator of a group chat on the Telegram app dedicated to Isis propaganda, which was used by suspected extremists to communicate, said deputy prosecutor Laure Vermeersch, as quoted by AP.

A source close to the investigation told AFP that she also "expressed her own intention of taking action".

Vermeersch said that no specific targets had been mentioned. The girl has been remanded in custody.

The girl had no previous criminal recorded, and was arrested in an anti-terror raid last Thursday in the Paris suburb of Melun. Prosecutors are attempting to trace other members of the Telegram group.

The arrest follows a series of terror attacks in France claimed by the Islamic State group. On 14 July Tunisian Mohamed Lahouaiej-Bouhlel drove a truck into crowds watching a Bastille Day fireworks display, killing 85. Twelve days later two Islamic extremists stormed a church in Normandy, holding parishioners hostage and murdering an 85-year-old priest.
