BERLIN, December 20 /TASS/. A 23-year-old Pakistani immigrant, Naved B, can be the perpetrator of the recent Christmas terror attack in Berlin, the German newspaper Welt reported on Tuesday citing its own sources. The German police believe that the man used the "Balkan route" to enter Germany last year.

A truck rammed into a crowd of Christmas shoppers at a fair in downtown West Berlin, on Breitscheidplatz near Kurfurstendamm Street at around 8:20 p.m. The truck steamrolled on for another 80 meters deeper into the market’s territory. As a result, twelve people were killed and 48, some in critical condition, were taken to hospital.

Russia’s Ambassador to Turkey, Andrei Karlov, was gunned down in Ankara by an assailant who turned out to be an ex-Turkish policeman on Monday.

Terror attacks, having become commonplace, are ominous signs of change taking place in the world, Russian Deputy Foreign Minister Oleg Syromolotov said on Tuesday commenting on the cold-blooded murder of Russia’s Ambassador to Ankara, Andrei Karlov.

"The world is changing. Terrorist attacks, which used to occur before, were a catastrophe followed by months of discussion. Today, terror attacks take place several times a day. They have become commonplace and this is a terrible tragedy," Syromolotov stressed.
