A mock invasion of Sweden and Norway has been carried out by 33,000 Russian troops, a US security think tank has claimed. Tens of thousands of soldiers rehearsed a military takeover of Swedish and Norwegian territory near the Baltic Sea in March, security expert Edward Lucas said in a report for the US-based Center for European Policy Analysis (CEPA). The exercise also simulated the invasion of other areas including the Danish island of Bornholm, Finland's Swedish-speaking Åland islands, and northern Norway, according to the report, The Coming Storm.
