Nanny beheaded 4-year-old Russian girl in revenge for Syrian airstrikes.

“I took revenge against those who spilled blood. Putin spilled blood, planes carried out bombings. Why are Muslims being killed? They also want to live.”

Just days after a nanny beheaded a four-year-old girl in her care and brandished it outside a Moscow metro station a video has emerged of her revealing that she did it to avenge Muslims killed in the Kremlin’s campaign of air strikes in Syria.

38-year-old Gulchekhra Bobokulova from Uzbekistan was detained on Monday, after she was caught waving the child’s severed head outside a Moscow metro station.

The nanny gave her first detailed explanation of the horrific beheading in a video posted online and shared by many bloggers and sites.

In it she is being asked questions by an un-named person off camera.

Gulchekhra Bobokulova says that she did it to avenge Russian President Vladimir Putin, who announced in September that Russia would launch air strikes “against terrorist groups” in Syria in support of President Bashar al-Assad.

“I took revenge against those who spilled blood,” Bobokulova told an off-camera interviewer.

“Putin spilled blood, planes carried out bombings. Why are Muslims being killed? They also want to live.”

She also said she had wanted to go to live in Syria but did not have the money to do so.

There has been speculation about when the video was filmed, but in it Bobokulova wears the same clothes as when she appeared in court on Wednesday.

Bobokulova was reportedly shouting Islamist slogans as she carried the head of the girl outside the train station.

Reuters reports that a witness claims he heard her screaming about the murder of children in Syria.

A police source has told the Interfax news agency that details of two men linked to an “international extremist group” had been found among her contacts but police have said Bobokulova is mentally ill and have never linked her to any sterrorism-related offences.

A Kremlin spokesman dismissed the video saying her remarks should be regarded as those of someone who is mentally unwell.

“You need to regard anything that such a deranged woman says accordingly,” Dmitry Peskov, the spokesman, told reporters.

In a controversial move Russia’s national television channels have refused to cover the killing, with the Kremlin defending the decision saying since the subject was “probably too monstrous to be shown on television”.

38-year old Bobokulova told journalists when she appeared in court that “Allah ordered” her to do it.

Investigator Olga Lapteva told the court that Bobokulova was suspected of committing an “extremely serious crime” and that she should face “a mandatory prison sentence of considerably more than three years”.

The court ordered her to be held in custody for two months as investigations continued.

Investigators said they were still trying to establish if Bobokulova had any accomplices.

She is suspected of murdering Nastya who had suffered from learning disabilities and epilepsy, at the family’s apartment in north-western Moscow, before torching the home and fleeing the scene.
