A vehicular attack in Berlin, Germany, kills and injures multiple people at a Christmas market.

A Christmas market, also known as Christkindlmarkt (literally: Christ Child Market, but the term "Christkind" usually refers to an angel-like "spirit of Christmas" rather than literally the Christ Child), Christkindlesmarkt, Christkindlmarket, Christkindlimarkt, and Weihnachtsmarkt, is a street market associated with the celebration of Christmas during the four weeks of Advent. These markets originated in Germany, but are now held in many other countries. Christmas markets date to the Late Middle Ages in the German-speaking part of Europe and, in many parts of the former Holy Roman Empire that included many eastern regions of France. They became a popular Advent custom during the Reformation era.Dresden's Striezelmarkt was first held in 1434 and is considered the first true Christmas market; earlier markets of the season were "December markets". Early mentions of these "December markets" can be found in Vienna (1298), Munich (1310), Bautzen (1384), and Frankfurt (1393), Milan.In many towns in Germany, Switzerland, and Austria, Advent is usually ushered in with the opening of the Christmas market or "Weihnachtsmarkt". In southern Germany, Switzerland and Austria, it is called a "Christkind(e)l(s)(i)markt" (German language, literally meaning "Christ child market"). Traditionally held in the town square, the market offers food, drink and seasonal items for sale from open-air stalls, accompanied by traditional singing and dancing. On opening night at the Christkindlesmarkt in Nuremberg, and in some other towns, onlookers welcome the "Christkind" (originally boy Jesus, but often depicted as an angel-like girl), acted by a local child.

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 truck was eventually stopped by its automatic brakes. 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. An initial suspect was arrested and later released due to lack of evidence. Nearly five years after the attack, a man who was critically injured during the attack died from complications related to his wounds, becoming the 13th victim.The Islamic State of Iraq and the Levant claimed responsibility for the attack and released a video of the perpetrator, Anis Amri, pledging allegiance to the terror group's leader, Abu Bakr al-Baghdadi.
