BRUSSELS (Reuters) - Turkish President Tayyip Erdogan makes a long-awaited trip to Brussels on Sunday, officially a two-day state visit to Belgium, that will be dominated by EU meetings over Europe's migration crisis and the fight against Islamic State militants in Syria.
Moscow's commencement of bombing raids in Syria could bring Russian warplanes to the very borders of the NATO country, now itself being used as a base for U.S. and allied air strikes. The dangers of unintended clashes, and uncertainty over Russia's intentions, have raised concerns in Western capitals.
