A TEACHER has quit after admitting to watching porn during a physics lesson full of 13 and 14 year old pupils, despite saying it was “unintentional”.

Shocking footage showed Razif Nurgaliev, 62, who has been a teacher at the school in Bashkortostan for around 40 years, smirking while watching porn after setting work for his physics class.

He “unknowingly” displayed the X-rated footage to his class, after he forgot his laptop was connected to the main screen in the classroom.

The footage was filmed by one of the pupils from behind his physics textbook and went viral in Russia.

But the school, which is in Tashkinovo village, near Neftekamsk city, initially refused to suspend Nurgaliev.

Instead, a school source tried to blame the pupils for playing a prank on the veteran teacher.

Nurgaliev said he had been trying to open an online journal and did not intend to watch the explicit material.

However, he finally admitted: “I clicked on something, and some website opened.”

The school’s female headteacher, Rudania Burkhanova, described Nurgaliev as being shocked after the footage of him watching the explicit content went viral on social media.

But amid fury from parents, the teacher quit with immediate effect – even though the school had wanted him to stay after, until now, an exemplary career.

The school said he was “valued and respected at the school” and the broadcast of the lurid porn was “accidental”.

A school source also said it would be hard to recruit another physics teacher to replace him.

The school finally launched a review after the footage spread on social media.

In her official response headteacher, Burkhanova said: “A review is currently underway, comments will come later.

“I need to hear both sides: I have already talked to the children, the parents, and I will talk to the teacher.

“Only after I hear both sides will I make a decision. No comments yet.”

A law enforcement probe is also underway in the Russian region of Bashkortostan, and the laptop has been confiscated.
