U.S. President-elect Donald Trump called the attacks this week in Berlin and Ankara “terrible” on Dec. 21 and said he has been proven to be correct about his plans to impose curbs on Muslims immigrating to the United States. “What’s going on is terrible, terrible,” Trump told reporters, when asked about the truck attack that killed 12 people at a Christmas market in Berlin and the killing of Russia’s ambassador to Turkey by a gunman in Ankara, Reuters reported.
