The Crimean school shooter, 18, who killed 20 of his classmates before turning the gun on himself, became suicidal from bullying, his ex-girlfriend has claimed.

Yesterday, a girl claiming to be Vladislav Roslyakov's ex-girlfriend told Russian media he had spoken of taking revenge for being ostracised.

'He would say that he lost trust in people when his classmates began humiliating him for not being like everyone else,' a 15-year-old named as Zlata told the Kremlin-funded RT television outlet.

'Vladislav was always telling me about his frequent fights with people around him,' she said, adding that he 'didn't want to live' because of it.

Russian health minister Veronika Skvortsova told news agencies that authorities are preparing to airlift at least 10 people with severe injuries to top Russian hospitals for surgery.

Ms Skvortsova said: 'The kids' muscles have been "minced" with small metal objects.

'Those who have their organs ripped apart, we are finding metal balls in kidneys, intestines, in blood vessels. That is how powerful the blast was.'

This morning a ceremony attended by authorities from the Moscow-annexed peninsula, began in the centre of Kerch.

Security has been stepped up in the city of 150,000, which sits in the far east of Crimea and is where a recently-opened bridge links the Russian mainland to its new territory.

All central roads have been closed and locals have been laying flowers at the central square.

The mourning ceremony will be followed by a procession towards Kerch's new cemetery.

Five students are in comas after the attack and their condition is described as 'extremely grave'.

Among the dead - mostly students aged between 15 and 19 - were a mother and daughter, Svetlana and Anastasia Baklanova, aged 57 and 26.

Many of those hospitalised were injured by an explosion that blasted metal ball bearings and other items into their bodies.

President Putin said the killing was the 'result of globalisation' and the continuation of a trend that had begun in the US.

Many made a comparison with the 1999 Columbine High School shooting in the US, which left 13 people dead.

They described photographs circulating on the internet showing Roslyakov wearing a similar T-shirt to Eric Harris, one of the Columbine killers.

Investigators are working to establish the teenager's exact motive and whether he was working alone.

According to the Russian Kommersant newspaper, the teenager 'grew up in a rather poor family' with a disabled father. The paper said Roslyakov's mother is a Jehovah's Witness - a Christian organisation considered 'extremist' and banned in Russia.

His mother, Galina Roslyakova, a nurse in Kerch Cancer Clinic where some victims of her son's violence were brought, was said to have been among those who provided first aid to victims.

She is understood to have tried to take her own life after hearing what her son was alleged to have done.

It was the greatest loss of life in school violence in Russia since the Beslan attack by Chechen separatists in 2004, in which 333 people were killed during a three-day siege.

Terrified students could be heard screaming amid blasts from a shotgun in videos captured during the rampage yesterday.

Teenagers sprinted past bodies sprawled on the ground while others made desperate attempts to flee down a flight of stairs during scenes of chaos and confusion in the school.

The shooter, who is thought to have obtained shotguns and rifles with a hunting licence for which he passed a psychological assessment, also set off a homemade nail-bomb in the canteen which blew out the windows.

Chilling footage also shows the gunman buying ammunition before the massacre.

Initial reports from the scene, described the slaughter as a terror attack, before it was reclassified as mass murder.

Teacher Vladislav Miroshnikov revealed adults at the college in port Kerch 'sacrificed their lives' to allow students to flee amid scenes of panic when the 18-year-old stormed the premises with the Russian word for 'hatred' emblazoned on his shirt.

Kremlin-appointed Crimean chief Sergei Aksyonov told Russian news agencies on Thursday that it is possible that the attacker, identified as Vyacheslav Roslyakov, had an accomplice.

'The point is to find out who was coaching him for this crime,' he said. 'He was acting on his own here, we know that. But this scoundrel could not have prepared this attack on his own, in my opinion and according to my colleagues.'

But today, there were angry disputes over whether the killer was alone. Several eyewitness accounts from students suggested there was more than one gunman.

It was revealed he had legally bought his Turkish-made Hatsan Escort pump action shotgun after undergoing medical and psychiatric tests.

There is confusion as to what drove Roslyakov to attack college. Pro-Kremlin Komsomolskaya Pravda (KP) newspaper gave four versions, none of them linked to an attack from Ukraine.

One was that he had argued with his first girlfriend, who he had been seen with in the days before the attack.

A friend was quoted as saying: 'Vlad was not in the college on Monday. Maybe he quarrelled with his very first girlfriend? And he was so much upset he missed a day - and then decided to punish the whole world for his failure with a girl?'

Another theory is that he was a fan of bloody computer games.

A friend was quoted saying: 'Vlad has always admired those who killed their classmates. I talked to him about it once when we were first year students. I knew he had computer games where you shoot inside the school.

'But I did not think he may do something like this in reality. Roslyakov did not really talk about it, we discussed it just once.'

A third version portrays the boy as an 'outcast' humiliated by his family's 'poverty' and his 'poor clothes'.

Crimea's senior politician Sergey Aksyonov said: 'What he published on his [social network] account was not open to the public. Access to his account was restricted, he didn't have any friends.'

KP suggested investigators are checking if pressure from his peers was behind the attack.

Finally, the newspaper claimed checks are being made on whether he had been recruited by an Islamic group.

'The version that Roslyakov might have been involved in Islamic extremist groups is being considered.

'Experts are studying this student's mobile phone and social networks now. As soon as his gadgets are checked it will be clear if this young man was recruited by ISIS or not.'

Teacher Sergey Pasechnik, 30, said: 'I was in the class with my students when we heard the shooting. I took my students outside. Then I ran back into the building, two students followed me. There were many injured.

'The doors were torn out by an explosion, so we used these doors to carry out the injured guys. Ambulances arrived shortly after.'

The alleged killer's friend Denis told KP newspaper: 'He was always very closed person from the first course. He did not communicate with anyone, unless he needed something for studies.

'He has not attended lessons since Monday, like he was ill. I wanted to message him yesterday, but his page in VK (social media) turned to be deleted.

'We have metal detectors at the entrance, of course. But they react more to the coins in your pocket than just a metal bar.

'I wouldn't be surprised if he previously a gun to check the detectors. He usually carried a hunting knife with him.

'He loved military literature, history. Surely he could learn something from there.'

Student Margarita Kuksova said in an audio recording with a friend: 'There was shooting. We began to run. We jumped over the fence. I cut my hand. Can you imagine, we were shot?'

'We were running and the kids were lying there' she added, crying. 'My friend Dasha was killed in front of my own eyes. I saw how she fell down and did not move, anymore, can you understand?

'The boys were falling and blood was everywhere. All this in front of my eyes... I can not bear it... I cannot calm down. I'm shaking. I can not even stay at home. I'm so scared.'

Three days of mourning have been declared in Crimea.
