I don’t think so...The Christmas Market was in Strasbourg and it was a bombing, unless there was a later attack too.
On 19 December 2016, a truck was deliberately driven into the Christmas market next to the Kaiser Wilhelm Memorial Church at Breitscheidplatz in Berlin, leaving 12 people dead and 56 others injured. One of the victims was the truck’s original driver, Łukasz Urban, who was found shot dead in the passenger seat.
The perpetrator was Anis Amri, an unsuccessful asylum seeker from Tunisia. Four days after the attack, he was killed in a shootout with police near Milan in Italy.
Should note that 13,000 Afghan evacuees were sent to Ft. McCoy in WI.
