The female suicide bomber behind the Ankara blast that killed 37 people was in an all-girl terror cell, MailOnline can reveal.

Seher Cagla Demir blew herself up in the Turkish capital on Sunday causing death and carnage in the city centre.

Turkish media are reporting that Demir was helped by a second suicide bomber, identified by them as Ozgur Unsal, 26.

Demir, 24, a hotel and tourism management student, was already on the run from the Turkish security services at the time of the bombing.

Killer: Seher Cagla Demir killed 37 people when she detonated a suicide vest packed with nails in the middle of Turkey's capital Ankara on Sunday, March 13

Dead: Ozgur Unsal, 26, who the Turkish media have idenitifed as the second bomber

Terrorist: Demir was a members of the Kurdistan Free Hawks (TAK), and had trained in Syria where Kurdish separatist groups are known to have camps hidden in the mountains

Demir, identified by the Turkish Interior Ministry as a bomber, was a member of a five-strong, all-female gang of extremists who were on trial in Turkey for terror offences.

The women, which included three sisters, were charged with being members of an armed terrorist organisation and spreading terrorist propaganda.

But in 2013 when Demir jumped bail and fled the country to Syria, it is believed. The case is on-going and the last hearing with the remaining four women was in December.

The Turkish government said she spent time with YPJ, the Syrian Kurdish female militia in Rojava, Syria.

It is believed spent some time being trained at a military terror camp for the Kurdistan People's Party (PKK).

The PKK is a separatist movement considered a terrorist group by Turkey, which has led a campaign against the state for three decades.

She may have also gone to Qandil in Iraq, the mountainous borderlands of northern Iraq where the PKK has its headquarters.

Terror cell: Demir was already known to Turkish authorities, and was on trial for terror-related offences in 2013

Running: But the 24-year-old fled before a verdict could be reached, causing the trial of the all-female terror cell to collapse, and wasn't heard from until she blew herself up on Sunday

Rejected: Demir's brother has also pledged allegiance to Turkey, saying he 'liv

In Syria she joined the Kurdistan Free Hawks (TAK), a splinter group of PKK, which has claimed responsibility for Sunday’s attack.

In a statement, TAK said Demir had been fighting 'Turkey’s massacre and denial of the Kurdish people' since 2013.

'On the evening of March 13, a suicide attack was carried out... in Ankara, the heart of the fascist Turkish republic,' the statement said.

Ashamed: Her family have refused to collect her remains, leaving her to be buried in a municipal graveyard

Demir’s family, who live in Marmaraereğlisi, a coastal town 70 miles from Istanbul have disowned her – and refused her remains to be buried.

Her father Cemil dismissed her beliefs, saying: 'I refuse to accept her funeral if she has been involved.’

Cemil said he had gone to the police station to give a DNA sample so they could identify his daughter's remains.

Demir's older brother said he was proud to be Turkish added: 'For my motherland, my people, and the land under this flag, I'm ready to let my blood flow to the last drop.

'My condolences to those who died in this explosion in my capital, and I wish those who are injured a speedy recovery.

'I wish to God that this organization [PKK] and its supporters don't get another opportunity.

'God damn these people a thousand times who are trying to divide my country.'

Demir grew up Marmaraereğlisi where she attended primary and high school.

Her family moved to Marmaraereğlisi from Kars, in the north east near Armenia where one in five residents are Kurdish.

She is believed plotted the TAK attack in Syria and met up with Unsal in Ankara at the end of February.

The female suicide bomber is believed to have crossed into Turkey at the border at Rojava last month with a fake ID card.

Team: Demir and the second suicide bomber Ozgur Unsal met in Ankara last month and had carefully planned out their murderous attack, visiting the scene before putting the horrific plan into action

Murderous: Unsal's severed hand was found 300 metres from the scene, while Demir was said to be blown into hundreds of pieces. Unsal's family have said they will bury him

Distraught: A woman cries over the coffin of one of their victims during a commemoration ceremony

Grief: Relatives of Feyza Acisu one of the victims who was killed in an explosion weep over her coffin. TAK say the attack was a strike at the heart of 'fascist' Turkey

In Turkey she is said to have met a third man, named in the Turkish media as the ringleader. He is said to be behind the attack but was not killed in the massacre and is being hunted by the security services.

Demir and the ringleader stole a BMW and drove to Ankara where they met Unsal and carried out the bombing.

In Ankara, the three are said to have inspected the site to prepare for the attack.

Demir and Unsal, who lived with his mother in Ankara, were killed. Unsal’s hand was blown off and landed 300 metres from the scene.

His parents had separated and Unsal lived with his mother in Ankara.

His mother confirmed he died in the bombing. But said she believes he was used by Demir, and suggested he unwittingly took part in the attack. He was used as 'camouflage', she added.

'They infiltrated our family,' she told Haberturk. 'We haven't been told whether my son is a bomber or not. He's definitely not a bomber. He was lost because of his purity and clarity of heart.'

Unsal, who grew up in Zonguldak, near the Black Sea, had no known terror links.
