On April 4, Russia began a live-fire military exercise including air and sea targets in the Baltic Sea, just beyond NATO territorial waters. The exercise, which will continue for three days, comes one day after Baltic leaders met with President Trump at the White House. Latvian officials said Russia has never drilled so near its territory, and that rocket fires have forced them to partly shut down Baltic commercial airspace. The Swedish Transport Agency has also rerouted air and sea traffic. Russia’s Defense Ministry said that the exercises are part of routine training in the Baltic Sea, and that the exercises abide by international law.
