TOPSHOT - A serviceman patrols on the Grand-Place (Groote Markt) on the sidelines of the "winter wonders" Christmas market, in Brussels on December 20, 2016.
The 16th edition of the Christmas market with events is open from November 25 to January 1, 2017. Security was beefed up at Christmas markets across Europe after a lorry ploughed through a market in Berlin on December 19, 2016, killing 12 people and heightening security fears at the onset of the holiday season. The carnage in the German capital had particular resonance in France, which has borne the brunt of terror attacks in Europe for the past two years. / AFP / BELGA / HATIM KAGHAT / Belgium OUT (Photo credit should read HATIM KAGHAT/AFP/Getty Images)
