Some 9,000 troops from 20 NATO countries have been participating this month in military exercises in the Baltic Sea region, which has become strategically sensitive following Russia's invasion of Ukraine.
Sweden, which had joined the drills in the past, took part in the Baltops exercises for the first time in June as a full NATO member after joining the trans-Atlantic military alliance earlier this year. The weeks of training include sea mine sweeps, submarine detection, landings and medical response to mass casualty situations.
Their goal is to enhance interoperability of the forces and to highlight the allied commitment to joint security, officials said.
