The Italian president has attended the funeral of a 31-year-old woman killed in the Berlin Christmas market massacre as her heartbroken family laid her to rest.

Relatives carried Fabrizia di Lorenzo's coffin during the service at Sulmona Cathedral, in Sulmona, Abruzzo, Italy today.

She was one of 12 people killed by ISIS fanatic Anis Amri on Monday, December 19, when he ploughed his truck into busy stalls on Breitscheidplatz Square in Germany.

Her family and close relatives were the only ones allowed inside the intimate ceremony, but locals lined the streets and applauded as her coffin was carried to the cathedral.

President of the Republic Sergio Mattarella and Interior Minister Marco Minnit attended, and embraced the family, according to ANSA.

Her body was returned to Italy on Christmas Eve after her parents and brother flew to Berlin to bring her home.

Ms Lorenzo, 31, was a transport specialist working in Berlin, and the mayor of her home town of Sulmona, Annamaria Casini, confirmed a day of mourning as 'a sign of respect and participation in the profound grief of the family and the community Sulmona'.

In a heartbreaking plea for help, her cousin tweeted in the aftermath: 'My cousin (Fabrizia Di Lorenzo) not replying to us since yesterday night'

ORDEAL OF SPANISH STUDENT WHO SURVIVED ATTACK A young student from Spain survived the terror in Berlin with multiple broken bones but his life intact. Iñaki E. from Bilbao was at the Christmas market with three female friends when the truck-terrorist struck. Iñaki, 21, an Erasmus student, was walking with his friends when the lorry hit the shoppers and the flimsy Christmas huts, turning them into matchwood. He remembers the truck shedding a tyre before he was struck. The Berlin School of Economics and Law student suffered multiple fractures - a broken leg in three places and broken bones in his foot. He underwent emergency surgery Monday night. He was due to travel home on Thursday but is confined to hospital. His parents have travelled to Berlin to be at his bedside as he recovers. His mum told Germany's BILD newspaper: 'Mentally he is coping well. He said when he lay on the ground waiting for the rescuers he had not really taken in everything that was happening. 'The girls took it much worse than him even though they were not hurt. We have had to cancel his flight home, we do not know how long he will be here.' Advertisement

Ms Lorenzo's last tweet came on December 5, when she shared a scene from award winning film, The Best Of Youth.

Her many social media posts suggest she was both liberal and supportive of refugees in a country which has been divided over the migrant crisis and the more recent burqa ban.

In March she shared an interview with Polish sociologist Zygmunt Bauman who argued a spike in immigration is not related to an increase in terrorism.

She also directed her 246 followers to research which showed the majority of Muslims living in Islamic countries held negative views towards ISIS.

Stefan Wolff, the CEO of the company where she worked, said that he had taken news of the atrocity hard.

'As a German citizen I feel scared about the situation in Berlin, where an attack can happen at a Christmas market,' he told MailOnline. 'Any incident that hurts people is very bad.'

'We are a very international company, with employees from 20 nations,' Wolff added. 'Anybody who works here is highly skilled and driven to be excellent. But they are also open and friendly as well.'

As an employee of the company, Di Lorenzo would have been 'not an average consultant who always knows better – but someone who listens carefully and is very open and friendly.'

Attack: German police have said the Pakistani refugee arrested and accused of being the driver may be the wrong man and the real killer could be armed and on the loose

A senior police officer said: 'We have the wrong man... The true perpetrator is still armed, at large and can cause further damage'

Ms Lorenzo graduated from the University of Bologna with a degree in International Relations and Diplomacy in 2012.

She began working in Germany in November 2013, according to her LinkedIn profile, as a customer services coach for electronics company Bosch.

Just over a year later she joined supply chain management company 4Flow, where she worked as a transport specialist.
