A 19-year-old girl was today stabbed three times by a man with psychiatric problems who told police voices ordered him to make a 'sacrifice' for Ramadan.

It is understood the man, 32, stabbed the girl twice in the wrist and once in the abdomen at 4pm in Rennes, western France.

According to local media he attacked her while she was waiting for a bus outside the city's Lycee Chateaubriand, where she is said to be a first-year preparatory student.

The man, who said he was being treated for schizophrenia, told officers he was a Muslim before handing over the knife.

The attack comes a day after a jihadist killed a French police couple in a small town near Paris, in a stabbing inspired by the Islamic State group.

A witness claimed the knifeman was overpowered by bystanders, according to Rennes magazine Le Mensuel.

He was immediately assessed by a doctor and sent to a psychiatric hospital.

He told investigators he was being treated for schizophrenia and was supposed to receive an injection on the day of the attack.

The girl was said to be standing at the bus stop on Rue Mirabeau when she was attacked, Le Dauphine reported. The teenager's wounds are said to be not life-threatening.

'Voices told him that he had to make a sacrifice on the occasion of Ramadan,' prosecutor Nicolas Jacquet told AFP. Ramadan is the holy Muslim fasting month that began on June 6.

Mr Jawuet added that the man had been in and out of psychiatric wards several times.

An investigation has been opened into attempted murder.

It comes as an ISIS militant murdered a police commander and his wife at their home near Paris on Monday, before being shot dead by officers who rescued the couple's three-year-old boy unharmed.

Larossi Abballa, 25, stabbed Jean-Baptiste Salvaing, 42, nine times in the stomach at his home in the Yvelines department, north west of Paris, shortly after 8.30pm on Monday.

After a three-hour stand-off elite Raid commandos entered the building, where they killed Abballa.

Inside the house, they found the lifeless body of Mr Salvaing's wife, Jessica Schneider, who was an administrator who worked for the police force in Mantes-la-Jolie.

The only survivor was the couple's three-year-old son, who was 'extremely shocked but otherwise unharmed'.

After killing the couple Abballa recorded a 12-minute monologue to camera while in the couple's house in Magnanville and posted the video on Facebook Live.

In the video, Abballa says: 'We will come and find you the way I have found this policemen at his house.'

He also hinted at an ISIS attack on the Euro 2016 football tournament, saying: ‘We're keeping another surprise for the Euros but I won’t say anything more.'

And, chillingly, he also hinted that the son of his victims was also in danger, saying: 'I don't know what I'm going to do with the boy.'

The couple's young son was 'in shock but unharmed,' a prosecutor said, adding he was receiving medical attention.

Mr Molins said Abballa pledged his allegiance to ISIS three weeks ago and appeared to be following a recent order from ISIS leader Abu Bakr al-Baghdadi 'to kill miscreants at home with their families' during Ramadan.

Three men - 'linked to' Abballa - were arrested on Tuesday morning. They were described as 'acquaintances' and are aged 27, 29 and 44.

It also emerged today the knifeman was part of a recent investigation into a Syrian jihadist network.
