Russia’s Defence Ministry denied its jets violated Estonian airspace, saying they flew over neutral waters. That prompted NATO jets to down some of them, and Western officials said Russia was testing the alliance’s readiness and resolve. “Russia has violated Estonian airspace four times already this year, which is unacceptable in itself, but today’s violation, during which three fighter jets entered our airspace, is unprecedentedly brazen,” Foreign Minister Margus Tsahkna said. “During the flight, the Russian aircraft did not deviate from the agreed flight path and did not violate Estonian airspace,” Moscow added. I don’t like when that happens,” Trump told reporters when asked if he saw the Russian airspace breach as a threat to NATO.
