Here is today's map of the security situation in eastern Ukraine, according to the National Security and Defense Council:
Czech and Ukrainian activists demonstrated outside an arena in Prague on October 17 during a performance by the Aleksandrov Ensemble, the official choir of the Russian armed forces. Protesters held signs calling the chorus "the music of war and occupation." Inside the concert hall, a small group of protesters holding Ukrainian, NATO, and EU flags tried to disrupt the show during a guest appearance by Czech pop star Helena Vondrackova, but were quickly escorted out.
