Three Russian warships were sighted near the Latvian border, the National Armed Forces of the Republic stated on Twitter.
"In the Latvian exclusive economic zone, 18 nautical miles from territorial waters, on October 21, the Navy identified the Bira-class supply ship Irgiz of the Russian Armed Forces," the statement says.
It also notes that 13 nautical miles from the territorial waters of the republic, a Russian Sura-class buoy tender Kilektor 1 was seen, and at six nautical miles, a Smolny-class training ship was also spotted.
Earlier, the Latvian military repeatedly reported about the approach of Russian ships and planes to the borders of Latvia. Russian Federation authorities asserted that their actions are within international legal norms.
