Footage has emerged showing the moment a lorry ploughed into a busy Christmas market in Berlin, killing 12 people.

The hijacked truck appears from the left of the screen as it races towards the crowded Breitscheidplatz square.

Seconds later, panicked shoppers run from the area.

In the attack, people were mowed down and wooden huts selling Christmas gifts and food were flattened.

The dashcam footage was taken by a taxi driver who was waiting for customers outside the market at the Kaiser Wilhelm memorial church.

Meanwhile, police have carried out raids across Germany as a Europe-wide manhunt continues for Anis Amri - the main suspect in the massacre which has been claimed by Islamic State.

In unconnected raids, officers arrested two brothers on suspicion of planning to attack one of Germany's biggest shopping centres in the western city of Oberhausen late on Thursday.

Investigators were trying to establish what stage of preparation the plot was at and whether others were involved, police said.

Raids carried out over Berlin attack

Earlier, police hunting for Amri used stun grenades during a search of a mosque in the Moabit area of Berlin, according to Berliner Zeitung.

Amri was photographed outside the building during a surveillance operation in the hours after Monday evening's attack, the RBB website reported.

The failed asylum seeker is suspected of being behind the wheel of the truck during the atrocity that injured 56 people.

The Tunisian's fingerprints were found on the cab of the lorry, interior minister Thomas de Maiziere confirmed.

Prosecutors have warned the suspect, who was monitored covertly for several months this year, could be armed and have offered a €100,000 (£84,000) reward for information leading to his arrest.

Armed police were also seen at a Berlin apartment block and two apartments in Dortmund were also raided.

A spokeswoman for the prosecutor's office said authorities carried out searches in various locations in North Rhine-Westphalia and Berlin.

Berlin attack puts Tunisia under spotlight

"Anis Amri is believed to have been at those places previously. Based on a tip-off, a bus in Heilbronn [southwest Germany] was searched. There have been no arrests."

Officials said the 24-year-old had come to their attention in March after a tip-off that he might be planning a robbery to raise money for weapons to use in an attack.

They followed him until September, when it was decided there was not enough evidence.

Amri first entered Germany late last year and authorities had been trying to deport him after rejecting his asylum claim in the summer.

Berlin suspect's brother: 'Turn yourself in'

He is thought to have used six different aliases and three different nationalities. German newspaper Der Spiegel criticised authorities who "had (Amri) in their crosshairs and he still managed to vanish".

Rainer Wendt, the head of a union representing German police, said civilians are "rightly outraged and anxious that such a person can walk around here, keep changing his identity".

Amri's brother, Abdelkader, has urged his sibling to hand himself in.

In a measure to boost public safety and security, concrete barriers that were put up during a Berlin car race in May are being installed again to help protect Christmas markets.
