Finland has apologized to Russia for a maritime border violation, media reported on Friday.
Finnish mine sweeper Hameenmaa erroneously entered Russian waters on Thursday. The vessel had sailed some 600 meters into Russian territory, west of the island of Hogland in the Gulf of Finland, the Finnish News Agency STT reported.
Russia’s coast guard opened fire on and seized three of Ukraine’s vessels Sunday, wounding two crew members, after a tense standoff in the Black Sea near the Crimean Peninsula, the Ukrainian navy said.
Russia blamed Ukraine for provoking the incident, which sharply escalated tensions that have been growing between the two countries since Moscow annexed Crimea from Ukraine in 2014, and it has worked steadily to bolster its zone of control around the peninsula.
Earlier in the day, Russia and Ukraine traded accusations over a separate incident involving the same vessels, prompting Moscow to block passage through the narrow Kerch Strait, which separates the peninsula from the Russian mainland.
Once the situation had been noticed on the Finnish ship, it returned to international waters. Finland made the matter public on Friday.
The navy said the ship was involved in routine surveillance of Finnish territorial integrity and there was nothing provocative in its movements.
