Who were the Berlin Christmas market terror attack victims and what do we know about the Breitscheidplatz lorry crash so far?
A HIJACKED lorry drove into a Berlin Christmas market at 40mph, killing 12 people in a suspected ISIS attack.
Here we look at the victims of the atrocity and go through exactly what we know about the Christmas market massacre.
Who were the Berlin Christmas market terror attack victims?
Authorities say 12 people were killed when the truck smashed through the market.
Four dozen people were taken to hospitals for injuries, some of them serious.
Only six of those killed in the attack have been officially identified as German nationals, and one person feared to be among the victims is an Italian woman.
Fabrizia Lorenzo, 30, has not contacted her friends or family since the attack and did not turn up for work on Tuesday morning.
Her phone and metro pass were found at the site of the horror.
Members of her family are thought to be on their way to Berlin to look for her, as an appeal was made on Facebook for help.
Miss Di Lorenzo had been working for a transport company in Berlin for two years, but had lived in the Berlin since 2013, when she started working for Bosch.
She reportedly went to university in Rome before completing a course in international relations in Bologna.
Dalia Elyakim, an Israeli woman, has been missing since the attack on Monday.
She was last seen stood next to her husband at the market.
Her husband Rami was seriously injured in the attack and is fighting for his life in hospital after undergoing three operations.
The children of the couple, aged both in their 60s, have since flown to Berlin to give DNA samples as authorities attempt to identify Mrs Elyakim.
The body of the truck's original driver, a Polish man, was later found inside the cabin.
Officials say he was not responsible for driving the truck into the markets.
The Polish owner of the truck said he feared the vehicle may have been hijacked.
Ariel Zurawski said he last spoke with the driver, his cousin, around noon, and the driver told him he was in Berlin and scheduled to unload Tuesday morning.
He said: "They must have done something to my driver."
Police confirmed the lorry's original driver Lukasz Urban, 37, who was returning from transporting steel beams into Germany, was last heard from at 4pm.
Mr Zurawski, whose company is based in Gryfino in northwest Poland, said German authorities asked him to identify the victim from photos.
He said: "His face was swollen and bloodied. It was really clear that he was fighting for his life."
Lukasz Wasik, the manager of the trucking company, described Urban as a "good, quiet and honest person" devoted to his work.
"I believe he would not give up the vehicle and would defend it to the end if were attacked."
The company's transport manager, Lukasz Wasik, said the driver was 37-years-old and had been transporting Thyssen steel products from Italy to Berlin.
The identities of the 11 other victims are not yet known.
Authorities on Twitter urged people to stay away from the area, to keep the streets clear for rescue vehicles.
It was later reported in that cops had arrested the wrong man and that the 23-year-old Pakistani man arrested in connection with the atrocity was innocent.
The source said: "The real culprit is still armed at large and can cause new damage."
Police later confirmed they had the wrong person after finding no blood or gunpowder residue on him. He was released without charge and the hunt to find the person responsible for the attack continues.
The archbishop of Berlin, Heiner Koch, said he would hold prayers for the victims at the St. Hedwig Cathedral.
What do we know about the Breitscheidplatz lorry crash so far?
At round 8 pm local time a lorry drove for up to 80 metres into a busy Christmas market busy with locals and tourists.
The Federal prosecutor's office for terrorism cases has taken over the investigation.
The Welt daily reported that police raided a large shelter for asylum-seekers at Berlin's defunct Tempelhof airport overnight.
Berlin police declined to confirm the reports, but spokesman Winfried Wenzel said the suspect was being interrogated before police admitted they had the wrong man in custody.
The Daily Tagesspiegel newspaper said the man was known to police but for minor crimes, not links to terrorism.
But police eventually confirmed the 23-year-old Pakistani man arrested in connection with the atrocity is innocent.
The White House condemned "what appears to have been a terrorist attack."
It came less than a month after the U.S. State Department called for caution in markets and other public places across Europe, saying extremist groups including Islamic State and al-Qaida were focusing "on the upcoming holiday season and associated events."
