European Union foreign ministers will discuss whether to increase sanctions on Russia and how to help Ukraine when they meet in Brussels on November 17, EU foreign affairs chief Federica Mogherini said on Tuesday.

"Next week we will have a ministerial meeting in Brussels on Monday and there will be a discussion there, but I would say not just on whether to increase the sanctions but most of all how to support Ukraine in these difficult times," Mogherini told reporters in Berlin.
