European stocks are down, in part because the plane crash in Ukraine has spooked investors, Investing.com reported. The day before the crash, the United States raised its sanctions against Russia, creating the largest penalty package yet. Additionally, tension has been rife between Israel and Palestine since Israel announced a ground campaign.
