Russia has detained a French citizen for illegally entering the country from Estonia, the Federal Security Service (FSB) said on November 21. An FSB statement said the French citizen admitted that he illegally crossed the border by boat on the Narva River. EU and NATO member Estonia shares a 300-kilometer border with Russia, and tensions between the countries have increased since Moscow launched its full-scale invasion of Ukraine last year. News agencies citing the FSB reported that the individual was detained for up to 30 days pending trial, and a criminal case had been opened.
