模仿文本： We begin though in Russia and a reminder just weeks before the beginning of the Sochi Winter Olympics of the precarious security situation in the south of the country. At least 16 people have been killed and dozens have been injured after a bomb exploded in the central railway station in the city of Volgograd. It happened just before 1 pm when the station was packed with travelers heading to their New Year's celebrations, the main holiday in the Russian calendar.
