A hooded man shouting allegiance to Isis has stabbed a nursery school teacher in the throat in his Paris classroom.

Update: Paris police are now saying that the teacher made the entire story up. You can read the latest updates here.

The attack, which happened a month and a day after the jihadist massacres in France, took place before children arrived at a state nursery school in Aubervilliers, just north of the Paris city boundary.

Police, who are treating the incident as a terrorist attack, said that the teacher had been stabbed in the throat and stomach by scissors and a box-cutter. He was taken to hospital but his life is not in danger.

An eyewitness told police that he had heard the attacker shout; “It is for Daesh, It is a warning.”

Daech is the Arabic acronym for Islamic State. The jihadist group has been warning on social media that French schools might be the next target after the shootings and suicide bombings in the Paris area on 13 November in which 130 people were murdered.

The attack took place at around 7am on Monday in the northern Parisian suburb of Aubervilliers.

The teacher has been taken to hospital but has not suffered life-threatening injuries, according to French media.

Paris prosecutor's office spokeswoman Agnes Thibault-Lecuivre said anti-terrorism authorities are looking into the incident.

Le Parisien reports that an investigation has been opened by anti-terrorist police into attempted murder in connection with a terrorist enterprise over the attack.

France is still under a state of emergency following the 13 November terror attacks in which 130 people were murdered in the capital.

The unknown attacker reportedly armed himself with weapons he found in the classroom. He is understood to have been hooded, masked and wearing gloves.

He is currently on the run, reportedly armed with the box cutter and a pair of scissors.
