ANTALYA, Turkey (Reuters) - NATO's military commander accused Russia on Wednesday of making irresponsible nuclear threats, which he said were intended to make NATO think twice about how it responded to Russia's actions in Ukraine.

U.S. Air Force General Philip Breedlove, NATO's supreme allied commander in Europe, also voiced concern at an increase in fighting in several areas of eastern Ukraine despite a declared ceasefire.
