Heartbreaking footage shows bystanders’ desperate attempts to help victims of Berlin terror attack

: "At first we didn't have a clue what it was. There were loads of people screaming so we knew it was something major.

"We froze - we didn't know what to do. Then we decided to try to go back and help."

The footage shows people crouched over victims amongst the debris of the market stalls.

People can be seen rushing to cover the injured and dying in coats in the aftermath of Monday's atrocity.

The man said: "There was nothing I could do to help.

"It was chaos. It was horrible... shocking. The truck went right the way through."

A huge hunt is under way for the truck terrorist believed to be “armed and dangerous” Tunisian asylum seeker Anis Amri.

The 24-year-old was due to be kicked out of Germany today and had been under surveillance for months earlier this year.

Last night ISIS claimed responsibility for the outrage — which came amid growing concerns about Germany’s two main spy agencies.

Police and security services were racing against the clock to find the attacker before he strikes again.

They declared they were searching for the “dangerous criminal” while politicians warned that Germany was “in a state of war”.

Twenty-five shoppers and stallholders remained in hospital last night.

Fourteen of them were critically injured and Germany’s interior minister, Thomas de Maizière said some might not pull through.

A further 24 casualties had been treated and released.

They were mown down as the Scania articulated lorry deliberately ploughed into crowds in Breitscheidplatz — a square in the German capital — at 40mph.

It careered up to 80ft before stopping, ripping through stalls and tossing victims aside like dolls.

The truck, carrying 25 tons of steel beams from Italy to Poland, had been hijacked and its Polish driver murdered.

The bloodied body of Lukasz Urban, 37, was found in the cab’s passenger seat after the atrocity.

A British dad has spoken of how he and his family were forced to run for their lives to avoid the lorry as it ploughed into the market.
