STOCKHOLM (Reuters) -Estonia summoned Russia's charge d’affaires in Tallinn on Monday to lodge a protest after a Russian MI-8 helicopter violated Estonian airspace near Vaindloo Island in the Baltic Sea, Foreign Minister Margus Tsahkna said.

"This is the third such incident this year, a serious breach of international law," he said on X.
