Local Police will use the concrete panels as protection for Christmas markets and New Year's Eve celebrations.

The concrete blocks used as crash barriers for Berlin's Formula E race on the Karl-Marx-Allee in May are being redeployed to protect Christmas markets in the city following Monday night’s terror attack at Breitscheidplatz.

The concrete barriers will also be used to protect public areas around the Brandenburg Gate ahead of celebrations there on New Year’s Eve.

Twelve people were killed, and dozens injured, on Monday evening when a stolen truck ploughed through the Breitscheidplatz Christmas market, veering off Budapester Strasse and smashing into stalls and Christmas shoppers.

Following a request from Berlin Police, Formula E immediately provided its four-meter long and one-meter high concrete walls to the city for redeployment, free of charge.

Each element weighs four tons, and was specially-designed to create the Berlin ePrix track layout, which switched to the city center in 2016 following the inaugural race at Templehof Airport. The blocks have been stored in Kopenick, for future Formula E events in the city. Since Wednesday, they have been positioned at relevant locations at Christmas markets across Berlin.

The police, the fire brigade, and the Berlin technical emergency service (THW) have handled the logistics and deployment of Formula E’s concrete blocks.
